Seasons switch again: Ectinorhynchus common in SE Australian spring

As the seasons swing again, the stiletto fly fauna switches back again. The spring genera are showing up, especially Ectinorhynchus in Australia and New Zealand and Entesia in Chile. Phycus brunneus seems to be a perennial favourite in India, although Irwiniella is sometimes seen and Thereva seemingly restricted to higher elevations. As we move into the summer months, we should start seeing more observations of Acraspisa, Parapsilocephala and Agapophytus in Australia, Peralia, Penniverpa and Notiothereva in Chile and Argentina, and Thereva, Schoutedenomyia and Caenophthalmus in South Africa; hopefully we will also see some more Phycusinae and Xestomyzinae throughout subsaharan Africa this season. Of course, a close relative of Peralia, Anabarhynchus will undoubtedly make frequent appearances this year throughout Australia, New Zealand and maybe even further afield in the Pacific.
Ozodiceromyia and Thereva continue to be frequently encountered in North America, and Thereva and Acrosathe common in Europe, although these genera with soon disappear for the winter months.

Looking forward to many new observations, observers and identifiers in the rest of 2023 and into 2024.
