I caught this Periscelis sp. in Amersfoort, the Netherlands, on sap of a bleeding tree (Aesculus hippocastanum).In the netherlands we have P. annulata and P. winnertzi, but what is the difference between the species?
Greetings,

This looks like annulata, although the quoted differences are slight (and maybe not consistent)..make genitalia are definitive. There may be more species in Europe; Laszlo Papp has at least two new species to describe.

Hanging Oporto wine traps at a height of some (about 5 m) meters in trees like oaks, or India chestnuts (or whatever) to catch periscilidids it's a total waste. :(
Use Jopen Koyt beer instead. :p

Last year I collected 4 Periscelis specimens (2 P. annulata and two P. winnertzi) in wine traps hanging at a height of about 5 m in oak trees, so not a total waste :). I didn't collect any in the beer traps hanging in the same oak trees :(.
