Bob Carlson commented:
"Grotea appear to be somewhat unique among the ichneumonids in that the larvae consume multiple larvae of Ceratina and also eat some of the pollen or bee bread with which the Ceratina cells have been provisioned."
Life Cycle
Adult females search for twigs and stems containing larval chambers of Ceratina...and perhaps other bees that excavate nests in the pith of broken plant twigs and stems. They then drill through the bark or outer tissue of the stem with their ovipositor and deposit an egg on the bee larva.
