Large Square-headed Wasp
A large solitary wasp that nests in dead wood and provisions its nest with captured flies. Has a distinctively large, square-shaped head. Common in gardens and woodland.
Did You Know?
Nests in old beetle holes in dead wood, stocking each cell with paralyzed flies for its developing larvae.
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.
