Abstract
1. Phaonia mirabilis eggs are laid on the surface of water in tree holes. The eggs are white and have lateral flanges and a ventral keel.2. Trimorphism is absent during larval life, and, except for size, the newly hatched larva resembles the mature larva, having anterior spiracles, triforous posterior spiracles and complete buccal armature.3. The larvae are carnivorous and capture and devour mosquito larvae.4. Eggs hatch in 3–4 days. The duration of larval life is about 4 weeks and that of the pupal stage about 2 weeks.
