Stiletto Flies of the World's Boletim

Congratulations all! We have reached 300 species of stiletto flies identified on iNaturalist. Hopefully we can reach 400 hundred soon.

Please submit your photographs and comments about any aspects of stiletto fly behaviour and biology that you observe in the field. There is so much we still do not know about these flies. One interesting observation that is easy to see, is any evidence of swarming or lekking. We know this occurs in many species, but in different ways. From males hovering in swarms in backyard gardens (Ectinorhynchus spp.) to males sitting on a tree trunks and flying in a loop together and landing in the same place (Agapophytus pallidicornis, A. australasiae). We would love to see and hear about other examples you see in the field. Maybe add some images or videos too.
