Blotched Emerald

Comibaena bajularia (Denis & Schiffermüller, 1775)

A medium-sized bright green moth has four white spots, smudged with orange-brown markings, one on each wing. Two delicate white cross-lines cross the wings, and the cilia are white and brown barred. The adults will rapidly fade from their bright green colour to a whitish green. The larvae of the Blotched Emerald is rather interesting. Originally appearing a stumpy brown larvae, with a sparse covering of short hairs, the larvae will attach small cut-outs of the foodplant and attach them to this hairs, which will aid in camouflaging the larvae.

Local in southern England and Wales. In Dorset the moth is largely restricted to north and east Dorset, while in Somerset the moth is most frequent in south Somerset. At Wyke Farm, the Blotched Emerald is regular, and is likely breeding at the site.

The Blotched Emerald is typically found in mature oak woodlands.

The larvae feed on the leaves of Pedunculate and Sessile Oak.

The adults are on the wing during June and July, where they are most often observed attracted to light.

The larvae can be found from late July to earliest June, where it will overwinter as a small larvae. Larvae are best found by beating trees in spring, where the larvae, which attach bits of the foodplant to themselves for camouflage, may be knocked off vegetation.
