Wasps are Carnivores!
While adult wasps dine on plant nectar and pollen, their offspring are carnivorous. To provide their young with the ‘meat’ they need to develop, the adult female wasp will collect insects such as spiders and caterpillars, then paralyze them so they stay nice and fresh. Once she’s filled the brood chamber, she lays one egg on top.
The egg hatches and the wasp larva sucks the insects dry, leaving only their skeletons behind. When all the food is eaten, the larva spins a pupa case around itself, diapauses over the winter, and emerges the next spring as an adult wasp — ready to collect and paralyze more insects for the next generation. Without wasps, our gardens would be overrun with insects!
