Bonjour, On Sunday July 22/2012 morning, I shoot those Agelastica alni larva on Alnus cordata's leaf. And on one of these leaves I saw this scene : pat_der2003 attached the following image:  [79.78Kb] |

You can easily imagine on the second picture (see below) the raise of the larva : is it due to larvae's irritation from the sucking of the Chloropidae or is it some kind of deed seen in Coccinellidae's larva when they are pupating (sudden raise) ?

Could the two eggs laid on Agelastica alni's larva be Chloropidae's one ? Or should they be more obviously Tachinidae's eggs (or some kind of parasitic flies) ? Thanks in advance !!! Edited by pat_der2003 on 01-08-2012 19:56 |

Here (http://www.olivie...010/07/23/) we have the same situation and some explanation. It is probably based on that text: http://www.zin.ru...00/16.html. I don't think that the big eggs belong to the Chrysomelids. Here (http://www.comman....alni.html) Tachinids as well as wasps are listed as possible parasites. |
