Blotched Emerald Comibaena bajularia


Normally flies at night; males are attracted to light more than females. With age the green frequently fades to creamy white. Caterpillars start appearing late July but are difficult to spot because they attach leaf pieces to their bodies as a means of camouflage.

Oak Processionary Thaumetopoea processionea


Oak Processionary moths were accidently introduced to England in 2005. They are now established in Greater London and are able to defoliate whole oak trees. Their larvae can cause rashes, eye irritation and breathing problems. They should not be touched. The larvae are usually seen from late May until July and adults fly from July until September.

Puss Moth Cerura vinula


On the wing from May to July. Caterpillars (up to 65mm long) are seen from July to September feeding on Poplar and Willow usually low down on saplings. When ready to pupate the caterpillar makes a tough cocoon from chewed wood and silk. If disturbed by a predator the caterpillars raise the head and wave extendable pinkish flagellae from their twin tails. If this warning is ignored the caterpillar is able to squirt formic acid from a slit under the mouth as a defensive measure.
