Lymeon
Lymeon is a large genus of ichneumonid wasps in the subfamily Gelinae (tribe Cryptini), containing at least 80 described species with a predominantly Neotropical distribution. The genus is characterized by females that parasitize small cocoons of various insect groups and spider egg-sacs. A taxonomic review recognized 33 North American species, with 28 species recorded from Mexico alone. One documented host association involves a Lymeon species attacking egg-sacs of the orb-weaver spider Araneus vincibilis in Northeastern Brazil, where larvae consumed approximately 80% of spider eggs despite maternal guarding.
