H,

Im new in this forum.

Id like to know wich specie is this Diptera. I think is the genus Leucopis.

Ive take it in late may from Catalpa bignoniodes (eating Aphis gossypii) and in Abies pinsapo (eating Minadarus abietinus) in garden in Madrid (Spain).

Ive photos of larva and pupa, because Ive 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).

Thanks a lot Steve!!


If you say me your direction I can send you an adult.

If you think its easier I could try to make the genitalia and send you a Photo. Ive never do genitalia of Diptera but I use to do on Lepidoptera.

How can I make difference between Leucopis, Pseudodinia, Plunomia and Chamaemyia?Is there any key?

Are caracteristic of all the Chamaemyidae the horns on larva and puparia?

Hi Luis,
My address is below. Make sure you send males - females are of no use (with few exceptions). Better that I do the dissections. As for keys to genera - there are keys in the Palaearctic Manual, the Nearctic Manual, the Central American Manual, the chapter in the Bei-Bienko series, etc. For larvae/puparia - yes the posterior spiracles being placed on these horns is characteristic, but there are a some genera where they are not pronounced. They are always pronounced in Leucopis though.
Cheers,
Steve

In alcohol is best - makes the dissection easier, and I can mount them afterwards.
