Hí,
I´m new in this forum.
I´d like to know wich specie is this Diptera. I think is the genus Leucopis.
I´ve take it in late may from Catalpa bignoniodes (eating Aphis gossypii) and in Abies pinsapo (eating Minadarus abietinus) in garden in Madrid (Spain).
I´ve photos of larva and pupa, because I´ve raise a lot of larvas in mi litle laboratory, but I can only post 1 photo in the forum. Can also someone tell me how to post more of one photo in the Forum?
Yes, the several photos (larva, puparia, adult) are all Leucopis. There is no guarantee at all (and I find it unlikely, but certainly possible) that the species attacking these two hosts are the same species of Leucopis. That said, it is impossible to identify most Leucopis from photographs, since the male genitalia are absolutely critical to their identification. I'd be happy to take a look at the specimens if you have males. That said, there are no Leucopis species recorded from Mindarus aphids (although they sure attack them), and only a couple known from Aphis gossypii (but they are not known from the western Palaearctic).
