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 Robert Heemskerk attached the following image:  [183.39Kb] Edited by Robert Heemskerk on 27-01-2008 11:57 |

Hello, Robert! Robert Heemskerk wrote: The wings are really short and the white spotted patterns on the abdomen typical. Is this species Ectopsocus petersi? Looks like it (a nymph). http://www.brc.ac...llery.aspx Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

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, |

Hello, Robert! Robert Heemskerk wrote: Why do you think this psocoptera is a nymph? 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 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

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! |
