Hello

What kind of Tachinidae is this? Alophora? Phasia? Ectophasia?

Looks like a very small Ectophasia crassipennis

Hi all, I was just about to stick my neck out and say it didn't look like crassipennis - but I checked my specimens and I have one identical to this. It is however different from my other 3 specimens, which are larger; have 3 dots in the middle of the wing and are more orange on the abdomen - so, is this the female?

Hi Chris,


Yes, it is a female. There is a strong sexual dimorfism in Ectophasia (as in Phasia). Moreover, especially the males tend to be very variable. On the other hand, females of crassipennis cannot be reliable distinguished from a picture from those of oblonga.
But your confusion is no doubt based on the comparison of males and females.


Greetings


Theo

Thanks to the both of you. I'm taking notes and... I'm learning.

This is the male (crassipennis, that is)
