Celebrating and Caring for the Land

Spiny Tachina Fly

Paradejeania rutilioides, also known as the “Hedgehog Fly” visits late season flowers for nectar and searches for beetles, butterflies and moths to lay their eggs on. Once hatched, the larva will eat away at its host from the inside until it is ready to pupate at which time it exits the host and metamorphoses nearby.
