I mentioned earlier in the week, in my post about the sawfly larva Heterarthrus vagans mining the leaves of Alder, that I’d found that miner while checking out leaves to see what small creatures had been munching holes in their leaves. And my recent staring at holey leaves on other trees and shrubs, in other locations, has produced a nice variety of Sawfly larvae, some that look like regular caterpillars, others like slimy slugs. I’ve linked the names to the Sawflies of Britain and Ireland website for those interested in more information on each species.

Caliroa annulipes on Hawthorn

Caliroa cerasi, also on Hawthorn

An unidentified Cladius species, on Field rose

The one that looks like bird poo, Eriocampa ovata, on Alder

One of the bum-waggling species, Euura pavida, on Willow

Another bottom waggler, Nematus septentrionalis, on Birch. I love how their munching has created a heart from their leaf.
