Hantsmoths

Very rare immigrant (less than 10 previous UK records) from mainland Europe, appearing in southern England. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan male 36-39 mm, female 40-46 mm. Similar to Oak Processionary T. processionea, which see for differences. Distinguished from Pale Eggar Trichiura crataegi by the comma-shaped marking in the centre of the forewing. Larva feeds on Corsican Pine and Maritime Pine, living gregariously within a silken web, causing sufficient damage to be a serious pest in some areas, no evidence of breeding in the UK. The caterpillars release urticating hairs, which may cause severe irritation of the skin and mucous membranes, often leading to strong allergic reactions in humans and small animals. Occurrence should be reported to Department for Environment, Food and Rural Affairs
