Yellow Ophion
A laterally flattened, tawny-yellow parasitoid wasp active at dusk and after dark. Its larvae develop as internal parasitoids of noctuid moth caterpillars.
Did You Know?
Its laterally compressed abdomen is thought to help it slip between grass blades when searching for host caterpillars.
Large-headed Resin Bee
A tiny black resin bee with a disproportionately large head that nests in beetle holes and hollow stems. It uses plant resin to construct partitions between brood cells.
Did You Know?
Its oversized head allows it to perfectly plug the entrance of its narrow nest cavity like a living door.
