Hi, Yesterday I saw this young Araneus diadematus spider in my garden. I took a photograph because of its nice colours and then noticed a yellow "swelling" on the side of its abdomen that is obviously a larva. I know Pompilid wasps burying paralyzed spiders with an added egg, but I did not know that unburied lively spiders can be attacked by parasitic larvae. Which insects can be such parasites? Thanks for any information, Sundew |

it is probably an Ichneumonoidea wasp. |

Pompilidae wasps only paralyze them... and then they give the spider to their larvae... and the spider is ate alive (it is like a dead-alive)... Sphecidae wasps predate on spiders, for example. And Ichneumonoidea wasps parasite the spiders. In diptera, only the famous Acroceridae flies parasite them. Acrocerids are really true ENDOparasitoids of spiders. |

Reminds me of a polysphinctine pimplid larva, but the ones I have seen were always on the anterodorsal part of the abdomen. Nice photos  |
