It is a grate pleasure to see name of Josef (Iosif) Porchinsky on that site.
Porchinsky described several species (not only in Diptera). He also wrote several wonderful articles on life history of Lucilia bufonivora, Hydrotaea dentipes, Stomoxis calcitrans ect? I?m afraid being in Russian this works mostly are not well known.
Porchinsky worked and lived in S-Petersburg.
