More Details

Taxonomic Complexity

The Toxomerus contains over 144 in the Neotropics and remains relatively understudied. Many species lack comprehensive identification , and larval biology is poorly known for most.

Larval Biology Uncertainty

While the Toxomerus was long assumed to have predatory , some have been discovered feeding on pollen. The specific larval feeding habits of T. corbis have not been documented.
