Range and population observations on some of the more commonly reported cynipid galls in the Eastern US.

Was bored at work today waiting for a bioinformatic analysis to run, so decided to make some notes on the distribution of the more commonly reported oak gall wasps. Also included here are some remarks on the local populations of a few species that I have observed over several years.

Acraspis erinacei – generally more northern, present but less common in the south. In Ohio, one of the most common and most consistent year-to-year.
Acraspis quercushirta – Centered on Appalachians and East. Based on the map, looks to be most common on Q. montana, compared to its other hosts.
Acraspis macrocarpae – Northern distribution, also on Q. gambeli in the Rockies, has extended beyond the native range of its host to cultivated trees in Alberta, present in both Calgary and Edmonton as well as Missoula, Montana. Absent from the south.
Acraspis pezomachiodes – more northern as well. More compact distribution compared with A. erinacei, with which it is found often in Ohio. Very common in Ohio and consistent year-over-year populations.
Acraspis prinoides – interesting Midwest centered distribution, more reported on Q. muehlenbergii than Q. montana? Given the host specificity of Acraspis species and Andrew Hipp’s recent oak phylogeny, we should rear some of these to confirm they are the same species. Uncommon in Ohio, very rare to find a tree with more than a couple.
Amphibolips acuminata - Mid-Atlantic centered distribution, with scattered observations in the southern states. Commonly found on Q. imbricaria in swamps in NE Ohio.
Amphibolips citriformis – southern distribution consistent with the ranges of its hosts.
Amphibolips confluenta – widespread, eastern NA. Has exceeded natural range of host – credible observations in Lubbock TX and Albequerque NM on cultivated trees.
Amphibolips cookii – more common in the north, esp the NE. Very common in Ohio, rare to find a group of Q. rubra without one. Consistent population year-over-year.
Amphibolips gainesi - Texas-centered distribution. Its hosts are throughout the SE, so may be some sampling bias given the great gall hunters that we have in TX.
Amphibolips nublipennis – more common north and east. Not a common gall in NE Ohio, I have seen it most frequently on Q. imbricaria compared to its other hosts.
Amphibolips quercuscinerea – almost exclusively Florida. Supposedly hosted by Q. incana, which has a wider distribution, but is probably undersurveyed.
Amphibolips quercusinanis – widely distributed but not as far south as A. confluenta. Very common in Ohio and consistant year-over-year. In my area much more common than A. confluenta.
Amphibolips quercusjuglans – widely distributed in eastern NA, has exceeded natural range of hosts in at least one example – Abilene TX. Anecdotally, seems to have population fluctuations locally here in Ohio, a mega crop of these in some years and few and far between in others, related to mast years in their oak hosts?
Amphibolips quercusostensackenii – more common in north. Very common and consistent year-over-year in NE Ohio. On nearly every pin oak.
Amphibolips quercusracemaria – Southern coastal plain/piedmont. Especially along gulf coast. Hotspot in DFW.
Amphibolips quercusrugosa – Midwest/midatlantic-centered distribution, although might be some sampling bias bc this one is not particularly charismatic. In Ohio most common on Q. imbricaria on wetland sites.
Andricus aciculatus – Southern distribution. Were extremely common at one of the Q. lyrata sites that I visited in S. Illinois. Never observed on Q. stellata in Ohio.
Andricus biconicus – Scattered throughout eastern US on Q. stellata. Seems to be more common in Midwestern Q. stellata populations than southern ones, based on the relatively few reports from the DFW area. Very common on Ohio post oaks.
Andricus chinquapin – mid-Atlantic centered distribution, but very possible that there is sampling bias, given how subtle these are.
Andricus coronus – seems to be more common east of the Appalachians, scattered elsewhere. I have found at only one random site in NE Ohio, and have looked at 1000s of pin oaks.
Andricus dimorphus – Distribution centered on Midwest, somewhat mirrors the distribution of its most common host, Q. macrocarpa. Promiscuous, host-wise, and has consistent year-over-year populations.
Andricus ignotus – rare in SE, scattered elsewhere. Fairly common on bur oak in Ohio.
Andricus nigricens – Midwest-NE centered distribution. Extremely common on Q. bicolor in NE Ohio to the point of which I use it to ID the tree.
Andricus pattoni – more southerly distribution, but found wherever Q. stellata are. Very common on Q. stellata in Ohio.
Andricus quercusflocci – even distribution in E. NA. Seems to skew slightly more southern than other Q. alba galls given that is has only been observed once in Michigan, Minnesota or Ontario. Common in NE Ohio, though not as much as either of the Acraspis galls on Q. alba.
Andricus quercusfoliatus – Southern coastal plain and Texas.
Andricus quercusformosus – Eastern coastal plain-centered distribution. On my spring trip, this year was locally very common on Q.incana and Q. laevis in some Longleaf pine forests… seems to be rare elsewhere.
Andricus quercusfrondosus – Northern distribution (DFW hotspot). In Ohio, definitely more common on Q. macrocarpa than its other hosts and thus more common in the W. half of the state where that species is more concentrated.
Andricus quercuslanigera – Mostly southern coastal plain species, but has followed Q. virginiana wherever that species has been planted even to California.
Andricus quercuspeticola – widespread E. NA. Host promiscuous.
Andricus quercusstrobilanus – Midwest/midatlantic centered distribution, hot spot in Chicago (large bur oak concentration?). I have seen these by far most frequently on Q. macrocarpa compared to its other hosts.
Andricus quercusutriculus – Currently midwest/mid-atlantic centered distribution. But definitely suffers from sampling bias. Very subtle species.
Andricus weldi – Midwest/midatlantic. I suspect this is more common than reported bc it is somewhat subtle. Very common in NE. Ohio, esp on mature trees.
Atrusca quercuscentricola –An odd Missouri/Arkansas centered distribution – conspicuously rare from the very well reported DFW area. Has some color variation across the range, with the reds that are apparent in the Missouri/Arkansas populations not encountered as much farther east. Very common on Q. stellata in Ohio, esp at the darby plains sites.
Belonocnema kinseyi - Texas-centered distribution.
Belonocnema treatae – Florida-centered distribution.
Callirhytis clavula – more common north and east. Very common on Q. alba in NE Ohio, have not encountered elsewhere in Ohio.
Callirhytis favosa – Northern distribution, have noticed population dynamics in this species, common some years and rare in others.
Callirhytis furva – eastern US, in NE Ohio undergos extreme population fluctuations, anecdotally have noticed an every other year pattern, with this sometimes being the single most common gall and being much lower in alternate years – one of the most common galls in NE Ohio in summer 2020 and have only seen a couple times 2021.
Callirhytis gallaestriatae -- Seems to be northerly distributed but could be sampling bias given that these are extremely subtle. Fairly common in Ohio, very early in spring (before leaf out).
Callirhytis infuscata – interesting distribution mostly on a diagonal line from Toronto ON, to DFW, probably sampling bias. Not common in Ohio.
Callirhytis lanata – more common north and east. Very common in NE Ohio, hard to find a Q. rubra without one.
Callirhytis piperoides – northeast centered distribution. Not common in Ohio.
Callirhytis quercusbatatoides – S. Coastal plain and Texas.
Callirhytis quercuscornigera – Midwest/north Atlantic centered distribution. Probably most common on Q. imbricaria in NE Ohio, but fairly host-promiscuous.
Callirhytis quercusfutilis – Mid-atlantic centered distribution. Common in NE Ohio and most frequently seen on Q. alba and Q. bicolor.
Callirhytis quercusgemmaria – scattered E NA. Not common in NE Ohio, but subtle and so probably underreported.
Callirhytis quercusoperator – common on the east coast, scattered elsewhere (rare in NE Ohio).
Callirhytis quercusventricosa – Scattered distribution E NA. Very local populations in my experience. Anecdotally, seems to like less disturbed spots than many other species. Massive host list but I have only observed on Q. imbricaria in NE Ohio. Unlike other Q. imbricaria galls, I have found this one more frequenly on dry sites.
Callirhytis seminator – Widely distributed across E NA but more common East of the Appalachians (uncommon in NE Ohio). So showy as to be relatively over-reported.
Callirhytis vaccinii – Exclusively in Texas.
Disholcaspis cinerosa – Texas-centered distribution.
Disholcaspis globosa – More common Appalachians and east. Rare in Ohio.
Disholcaspis pruniformis – Texas-centered distribution.
Disholcaspis quercusglobulus – Wide distribution in Eastern NA. Very common and consistent populations year-over-year in NE Ohio.
Disholcaspis quercusmama – Somewhat northern distribution, where its two most frequent hosts (Q. macrocarpa and Q. bicolor) are more common.
Disholcaspis quercusvirens – E coastal plain and Texas, especially common in Florida.
Disholcaspis spongiosa – Southern distribution
Dryocosmus floridensis – Scattered distribution in E. US. Very common in NE Ohio on Q. imbricaria.
Dryocosmus quercuspalustris – more common north and east, but a hot spot in DFW as well. Extremely common in NE Ohio, and consistant year-over-year.
Kokkocynips decidua – NE centered distribution, Minnesota also a hot spot. Rare in Ohio (never personally observed).
Kokkocynips difficilis – Piedmont/coastal plain species. One of the few that looks to be more in the piedmont than the coastal plain, but could just be sampling bias.
Kokkocynips imbricariae – wide distribution E. NA, in NE Ohio most common on Q. rubra, but have seen on other host species as well.
Kokkocynips rileyi – more common in parts North and East, but a hot spot in DFW... might be some samping bias given that these are fairly tiny. In NE Ohio most common on Q. imbricaria and velutina, but have seen on most of the red oak group. Might have a couple of flushes in a year, seem to see fresh ones in June and again in late August/September.
Melikaiella tumifica – NE centered distribution. Present in Ohio, but not super common, easy to overlook
Neuroterus quercusirregularis - Seems like a trend to be more southern in distribution (but needs more sampling).
Neuroterus quercusbatatus – NE/Mid-Atlantic centered distribution. Scattered in NE. Ohio.
Neuroterus quercusvarrucarum – Scattered distribution in E. NA with hot spots (DFW, DC). Have noticed population fluxutions in this species, some years extremely common, some years rare in NE Ohio. On Ohio States main campus in Columbus was one of the single most common galls.
Neuroterus saltarius – Northern distribution, certainly more common than reported.
Neuroterus tantalus – Northern distribution, more common than reported. On nearly every Q. alba in NE Ohio.
Neuroterus umbilicatus – Midwest/mid-atlantic centered distribution, could be sampling bias as these are subtle. Easy to find, but not overly common in NE Ohio. Some year-to-year flux in populations.
Neuroterus vesicula – Midwest/mid-atlantic centered at the moment, but almost certainly subject to sampling bias.
Philonix nigra – more northern distribution. Some flux in populations, 2021 a low year in my experience.
Phylloteras nigrum – Midwest/midatlantic centered distribution, certainly some sampling bias here as they occur at a season (late September-October) when fewer people are looking. Not hard to find in NE Ohio, but not common either.
Phylloteras poculum – Midwest/mid-atlantic centered distribution. Common in NE Ohio but not as much as the Acraspis galls on Q. alba. Definitely more common on older trees in my experience.

Phylloteras vollutellae – Northern distribution, definitely more common in areas where host is common (Present in W. Ohio, have not found in NE Ohio). Seems to be very common in Chicagoland where Q. macrocarpa is king.
Trigonaspis polita – Disjunct peaks in population in Texas and Florida, scattered observations up the E coast.
Trigonaspis quercusforticorne – Far northern distribution. Chicagoland and Massachusetts the farthest south observations. Majority of observations in Canada.
Zopheroteras compressum – more northern distribution, although sampling bias definitely probable. Another late season gall.
Zapatella quercusphellos – NE/Mid-Atlantic centered distribution. Infrequent in NE Ohio, most common on Q imbricaria here.
Zopheroteras guttatum – more common North and East, with a hot spot in DFW, more common than reported (tiny size). Flucuates in population, in sync with C. furva.
Zopheroteras sphaerula – NE/midwest centered distribution, sampling bias a possibility as this is another tiny one.

Overall trends and questions
Many Q. alba galls (with the notable exception of DQG, A. quercusflocci and C. seminator) are more common in the north, Q alba rarer or more scattered in the South?
Several red oak galls are focused more north and east as well, again with a few notable exceptions. Does this just represent sampling error, is it a factor of tree density or something else?
Post oak galls tend to be southerly distributed, which makes perfect sense, but many are underreported in areas other than Texas… if you live in an area with post oaks go out and take a look. I think one of the problems here is that in areas other than TX/OK post oaks are not common in cultivation, and thus you need to go to rural areas to find them.
What drives population fluctuations in some species? Is it just simply that they emerge every other year? Do these fluctuations represent an adaptation to reduce parasitoid pressure?
How are some species able to expand their range beyond the range of their host while others stay quite local? Are some species more adaptable to wind distribution or hitching a ride on nursery plants?

Surveying of common but less charismatic species, particularly small bud galls and integral leaf galls.
Surveying of the less populated southern states - Northern Louisiana across through South Carolina.
Surveying of non-summer species - spring and fall species are less well surveyed.
Surveying of less common oak species that may be strong hosts for some of these "rare" species

Anyone with any thoughts on any of these species? Do your local populations match these observations or contradict them?

Tips for Gall Hunting

Tips on Gall Hunting; Where and When to Hunt for Galls

Think about sites that have mature trees with low-hanging branches. Sites that have been quite good for me include city parks, cemeteries, and forests with lots of edges where the forest meets open ground, such as fields or prairies. Galls are often on large tree species, so closed forest environments can be more difficult, especially if you are looking for galls on shade-intolerant species such as oaks. Forests with edges next to prairies are particularly fantastic as you can find galls on the trees and the herbs.

Areas of high human impact have some influence on the frequency of gall species, at least the more uncommon species. However, do not disregard manicured areas such as arboretums, city parks, golf courses or even tree lawns as they will often have galling species. For example, I found 20 or so gall species on the highly managed "Oval" on Ohio State University's main campus. Diversity does tend to be lower in these spots but do not discount them as a place to look.

If you just want to find a gall (any gall), seek out sites with plant species that have a huge diversity of galls. Examples of species with large gall diversity include; Quercus (particularly alba, coccinea, stellata), Carya (in late summer many of these will have a half dozen gall species), Celtis (many here in Ohio have 5-6 species on a single tree, although I am not sure how far east some of these go), and Solidago/Euthamia. iNat distribution maps and geotags can be useful for finding these sites. Another recommendation if you are looking for a particular host is to do a search for the common name of the host on your state's DNR website, they will often list some of the common species that are located at a given nature preserve or state park.

If you are looking for a specific gall, try to find a site where the host is regionally native and common. Trees that are native and more common in a region will tend to have higher diversity. For example, Quercus macrocarpa and Quercus muehlenbergii are native but uncommon in NE Ohio. I have found far fewer gall species on them in this area compared to western Ohio where both species are much more common. Hackberry, Celtis occidentalis, is another example of this, it becomes much more common as you move south and west in Ohio and the diversity of galls seems to increase in that direction.

If you notice that a particular tree has a large number of galls, keep visiting that tree repeatedly through the course of the year and even over multiple years, and you will likely run into new species. It seems like some trees have something like a susceptibility factor or alternatively, some kind of environmental niche like wind direction that seems to make them more galled than others. These trees have been a rich source of new species for me.

Mid to late summer (July-September) is the best season for hunting galls in Ohio. The highest number of species will be around during that time. However, if you want to find rarer or underreported stuff, look for galls during what might seem like the offseason. For example, early spring (March-May) has many interesting oak bud galls. October has another subset of oak galls that appear just as the leaves are turning that don't often get reported. November and December after the leaves fall can be a good time to look for galls in the leaf litter of more closed forests.
