Size: 6mm; Date: Mid March in Vienna Cheers, Lorin Edited by Carnifex on 09-04-2019 22:05 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

Are you using the Tschorsnig key? There it is stated that Periscepsia starts to appear in Mid May.... Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

From these pics, it seems that the left humerus differs from the right, probably bevause some are broken off ? You can check the pores. Theo

Is the conclusion plausible? Cheers, Lorin Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.
