Thread subject: Diptera.info :: Eristalis arbustorum
#1
Can I have some reassurance please? I am reasonably confident that these two are male and female of
Eristalis arbustorum, but would like someone to confirm it.
From 19 August 2006, east London cemetery park.
Female first.
#2
Female again. Face completely dusted except for tiny dot which I assume is just rubbed. Black tarsi, mid tibia black in apical half. 9mm.
#3
Male. 10mm. Much hairier than female on abdomen.

Sure looks like
arbustorum. But to exclude
abusivus:
can you give us a close look on the antennae of both sexes and the upper side of the head of the male?
#5
OK will do - what are we looking for?
#7
Another close up of female.
#8
And another close up of the female
#9
And a close up of the male

Another close up of the male

And another close up of the male

This is a different female, collected a month earlier on 22 July 2006, in the same east London cemetery park. I see that Stubbs says that the easiest way to distinguish
E arbustorum and
E abusivus is to check that the mid tibia is clearly bicolour (arbustorum) and not entirely pale (abusivus). Is this character reliable?
