Members of this genus are particularly well known as hyperparasites which attack the 

 cocoons of Braconidae or other Ichneumonidae, but there are also many species which attack the 

 egg cocoons of spiders. Apparently, some species of Gelis can sometimes be primary parasites in 

 the cocoons of sawflies or small Lepidoptera.
