Dance Fly
A predatory fly in which males present silk-wrapped insect prey as nuptial gifts to females. Mating swarms form elaborate aerial dances over landmarks.
Did You Know?
Some males cheat by wrapping inedible items or empty silk balloons to trick females into mating.
Ochraceum Black Fly
A small orangish-brown black fly that is the principal vector of onchocerciasis in Central America and southern Mexico. It breeds in small, fast-running mountain streams. Biting activity peaks in the early morning and late afternoon in coffee-growing regions.

The Americas are close to eliminating onchocerciasis thanks to mass ivermectin distribution targeting this vector's parasite.
