hi other insectforum,

I found this little Collembola sp. on a chopped treetrunk (old beech)
The wings are really short and the white spotted patterns on the abdomen typical.
Is this species Ectopsocus petersi?

size: ~2mm
place: Amsterdam forest

Looks like it (a nymph).

hi Juergen,

Thankx for your reaction,

Why do you think this psocoptera is a nymph?
Perhabs there are also Ectopsocus sp. with short wings?
E. briggsi is very common, couldn't it be E. briggsi?

Robert,

Ectopsocus petersi and briggsi (*) are very numerous here in the garden and at the house, but I have never seen a brachypterous individual. The nymphs always were smaller than the adults - indicating that they were really nymphs.

(*) At least I think, they are these two species. They look quite different, matching clearly the pictures of the two here:

http://www.brc.ac...llery.aspx

If I am right, then E. petersi is more abundant here than briggsi (95:5).

E. briggsi is very common, couldn't it be E. briggsi?


See above: (*)
Best regards,
Jürgen

I 've just read a article in Dutch where Noordijk & Berg found some macropterous and brachypteer Ectopsocus briggsi! (long-winged and short-winged) in Amsterdam and other places.
So I think the short-winged above here, could be a brachypterous Ectopsocus.

I'm gonna look better to the difference of these species in the pictures.
Thanks again!

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
