The subfamily Hemileucinae (Lepidoptera: Saturniidae) includes species whose stinging larvae can affect human health when their spines connected to poison glands come into contact with the skin (erucism). The genera Lonomia, Hylesia, Dirphia and Automeris are present in Panama and are of medical importance. Recently in green areas of Boquete, Chiriquí province, numerous presences of gregarious larvae provided with thorns was observed on the trunk and foliage of a palo santo or pito tree (Erythrina fusca), so the aim of the present study was to identify the species of stinging larva associated with this legume. To do this, foliage samples and seven larvae were collected with the help of plastic containers, avoiding direct contact with them. The specimens were passed through hot water and then placed in 70% ethanol for observation and identification in the laboratory, with the help of specialized literature. According to the results, the species corresponds to Dirphia avia (Stoll, 1780), present in Central and South America and with previous reports in four other locations in the country. However, this finding represents a new report for the Boquete district, Chiriquí province. In conclusion, the species of stinging larva associated with E. fusca in green areas of Boquete corresponds to D. avia, so it is recommended that people avoid direct contact with the insect and if an accident due to erucism occurs, seek medical attention.
