The Gothic moth is well distributed throughout much of the British Isles.

The species is found in a variety of habitats including gardens and woodland but shows a preference to damp and wetland areas.

It has a wingspan of approx 37mm and flies at night between June and August when it is occasionally attracted to light.

The adult moth shown was attracted to an MV light in North Cornwall on 14th July 2013.

The Gothic Moth caterpillar

The caterpillars feed on a variety of herbaceous and woody plants including plantain, dock, dandelion, blackthorn and sallows.

The caterpillars overwinter as late instar caterpillars during which time they continue feeding in mild weather, becoming more active as the temperature warms up.

The caterpillars are nocturnal feeders and not frequently observed during the day.

Identification of the Gothic Moth caterpillar

At a glance this is a pretty uninspiring looking caterpillar and similar to several other noctuid moth caterpillars.

The fully grown caterpillar reaches 45 mm in length and has variable dull cloudy shades of reddy brown, grey and sometimes hints of green. Perhaps the most obvious feature that can help identification are the orange spiracles.

The caterpillar of the Old Lady, Mormo maura, is similar, also having orange spiracles but is larger, reaching 60-70mm in length.
