Hi, in a conservation area near Ansbach, Middle Franconia I found 3 males and 2 females on sycamore leaves this morning.
I think it's Aedes [Hulecoeteomyia] koreicus and like to hear the experts comments.
Thanks a lot!

Aedes (Ochlerotatus) annulipes/cantans by Tony Irwin

---

male, thorax

---

female

I'm not really familiar with koreicus (or japonicus), but from what I can discover, they would both have a more clearly striped thorax, white scales on the occiput, and white scales towards the base of the hind femur. These individuals appear to me to be Ochlerotatus, near annulipes.

Hi Tony, thank you very much - and I think you're right. I will try to find those again tomorrow morning to take more fotos - especially of thorax and abdomen.

Yes, getting some lateral shots always helps! |t

and here they are:

and another one
Length of basal ring tarsomere 2 < half of tarsomere length = cantans?

(I've invited one male to stay with me this morning - if we need more details...)

Thanks, Eric

Your photos confirm that these are not koreicus or japonicus, but whether they are annulipes or cantans? - well, I often find these difficult to separate. Structures in the male genitalia seem to be the most reliable characters.

Yes, clearly not koreicus or japonicus - thank you very much, Tony!
What do you think of MosKeyTools hint, length of basal ring tarsomere 2 < half of tarsomere length = cantans while length of basal ring tarsomere 2 >= half of tarsomere length = annulipes?

The length of he basal ring does seem to vary quite a bit. If it's clearly half or more, then I'd say annulipes; if it's clearly a third or less I'd say cantans. The problem is the (many) individuals where the ring is between a third and a half!

Thanks again, Tony. So I change the title accordingly.

Kind regards, Eric
