Flesh Fly

A large gray fly with three black longitudinal stripes on the thorax and a checkered abdomen. Unlike most flies, females give birth to live larvae rather than laying eggs.

💡

Did You Know?

Flesh flies are larviparous, depositing live first-instar maggots directly onto food sources, giving their offspring a developmental head start over egg-laying competitors.

Parasitic Wood Wasp

A small, dark-bodied wasp-like insect with a flattened head and short antennae inserted below the eyes. It is among the most primitive parasitoid Hymenoptera.

Did You Know?

Orussidae are considered the evolutionary link between sawflies and parasitoid wasps, making them key to understanding Hymenoptera evolution.
