Characterization of morphological and biological aspects of venomous caterpillars of the genus Lonomia Walker (Lepidoptera: Saturniidae) in Colombia

The genus Lonomia Walker, 1855 (Lepidoptera: Saturniidae) is of particular interest to the medical community, since the scoli of these caterpillars harbor a venom that induces hemorrhaging in humans. In Colombia, deadly encounters with Lonomia achelous (Cramer, 1777), have been reported since 2000....

description The genus Lonomia Walker, 1855 (Lepidoptera: Saturniidae) is of particular interest to the medical community, since the scoli of these caterpillars harbor a venom that induces hemorrhaging in humans. In Colombia, deadly encounters with Lonomia achelous (Cramer, 1777), have been reported since 2000. There is little information on the main biological and ecological aspects of this genus to help better understand and develop prevention strategies. This study aimed to describe morphological and biological aspects (especially of immature stages) of four recently reported species of Lonomia in Colombia that pose a risk to humans. We collected caterpillars and adults from five localities and reared them under laboratory conditions. Specimens were identified using DNA barcoding and dissection of adult male genitalia. We provided the first description, to our knowledge, of part of the life cycles of Lonomia casanarensis Brechlin, 2017 and Lonomia orientoandensis Brechlin & Meister, 2011 and the complete life cycles of Lonomia columbiana Lemaire, 1972 and Lonomia orientocordillera Brechlin, Käch & Meister, 2013. We also present the first records of the parasitoids of L. orientocordillera, and L. casanarensis and new host plants. This information will guide not only their morphological recognition and the identification of their parasitoids and hosts, but also will guide rearing methods of these and other Lonomia species in new studies to prevent incidents with humans and create specific antivenoms.
