Merodon equestris

Merodon equestris
Flatbush, Brooklyn, Kings County, New York, USA
June 7, 2020

Sinuous wing vein identifies Eristalis, one of the bumblebee mimics. Other characters:
- Tarsi (hind legs) are black, not orange, rules out E. flavipes, orange-legged drone fly, and E. oestracea, which is very rare, anyway.
- Range is too far south for E. fraterculus, which is rare, anyway.
- This leaves E. anthophorina, orange-spotted drone fly (the orange spots are not visible in either of the photos).

The strongly looped R4+5 vein
The strongly looped R4+5 vein and the re-entrant upper outer cross-vein (curving back toward base of wing) - Merodon equestris … male.
Eristalis has the R1 vein and R2+3 vein joining to form a short stalk which reaches wing margin (a longer stalk in Palpada) and the R4+5 vein and M1 vein join to form a short stalk reaching wing margin and not re-entrant.

Moved from ID Request.

Many Eristalines have the sinuous wing vein, not just Eristalis. Note open r1 cell (closed with a stem to the wing edge in Eristalis sp), thickened hind femur. Other details of wing veination point to Merodon.

I am unlinking these two images as this is a female and the other photograph of a male.

I think it might be a male?
