Hi Diptera's
Yesterday I found this kind of syrphidae, in a bucket of water.
I was wondering If ID could be possible from these pictures?
(I could not make a good topview)
Place: Netherlands, Almere

Greeting Robert

Hello Robert,
yes,
Eupeodes luniger (markings do not reach edges of tergites). That species seems to overwinter as an adult in the last few years. Last year I found one in early February.

Hi Robert & Jürgen
"markings do not reach edges of tergites" does not hold up when examining Dutch material of early spring Eupeodes. These blacker than normal specimens belong to Eupeodes corollae. There are lots, certainly last years, specimens of a winter generation. They lack the typical chromatic distinctive features of E. corollae. A recent example is this female:

There are very few sighting of E. luniger this early in the year in the Netherlands.
Kind regards,
Ectemnius

interesting! According to my observations
Eupeodes corollae is a mostly summer species here in northwest germany - if I identified them correctly... (I find especially the males rather distinctive). All
Eupeodes from late autumn or late winter showed the character I counted on ("markings do not reach edges of tergites"). And I never saw a typical
E. corollae male that late or early. Here are some females I found outside the "normal season". So they all are
Eupeodes corollae?
