Black-Headed Ash Sawfly
A small sawfly whose larvae have distinctive black heads and whitish-green bodies. They feed on the underside of ash leaflets, skeletonizing them.
Did You Know?
This species is often mistaken for moth caterpillars, but like all sawfly larvae, it has more than five pairs of prolegs on its abdomen.
Vapourer Moth
A moth in which males are russet-brown day-fliers while females are completely wingless and never leave their cocoon. Females lay eggs directly on their own pupal case.
