Lepidopterism due to exposure to the moth Hylesia metabus in northeastern Venezuela

Lepidopterism refers to a spectrum of medical conditions in humans that usually involves the skin and results from contact with the adult or larval forms of certain butterflies and moths. We analyzed the epidemiologic and clinical features associated with exposure to the moth Hylesia metabus between 1970 and 2002 in the Cajigal district, Sucre, Venezuela. Fifty cases of lepidopterism mostly affecting individuals under 18 years of age were identified during this period and manifested as pruritic dermatitis with or without associated respiratory symptoms. With increased travel to endemic areas of lepidopterism, travel and tropical medicine practitioners should be aware of the clinical spectrum of this condition.
