Eiparasitismus bei Zitterspinnen




Titel des Projekts: 
Eiparasitismus bei Zitterspinnen
Org. Einordnung: 


Pholcid spider females carry their egg-sacs with their mouthparts until the spiderlings hatch and it is probably for this reason that the eggs are not densely covered by a protective layer of silk as in most other spider families. It seems that few egg parasites have managed to access these protected eggs of Pholcidae. Only one case has previously been published in Pholcidae (Huber & Wunderlich 2006).

During recent trips in SE Asia and Brazil[1], several new cases of egg-parasitism in Pholcidae were discovered, and in some cases the female spiders were kept alive until the wasps emerged. Several different spider genera are affected, and it seems that at least four different wasp species are involved.
