Black-sided Calligrapher

Toxomerus corbis is a small hover fly in the Syrphidae, commonly known as the Black-sided Calligrapher. It is one of approximately 144 in the Toxomerus, a diverse group distributed primarily in the Neotropical region. The genus was historically assumed to have predatory larvae, though some species have been found to feed on pollen. are active , visiting flowers for nectar.

Taxonomic Complexity

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

Larval Biology Uncertainty

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