“…Unfortunately, the early stages of two other medically important species present in Colombianamely L. achelous and L. descimoni, are either insufficiently known for the former (e.g. in [26]) or undescribed for the later (though its venom was recently studied in [10]). This leaves DNA barcoding as the most reliable method for species identification of Lonomia caterpillars at the moment [1], unless these can be reared to adults, thus enabling identification through comparisons of the morphology of male genitalia (e.g.…”

“…The current treatment for envenomation by Lonomia is administration of an antivenom produced against Lonomia obliqua Walker, 1855 by the Butantan Institute of Brazil [ 9 ], which has proven to be effective in response to envenomation by three species in Colombia: L . descimoni [ 10 ], L . orientoandesis [ 11 ] and L .…”

“…In humans, this venom can cause a burning sensation, pain, and headaches [4], alter the coagulation system [5,6], and trigger other disorders, such as chronic or acute renal failure [7] and cerebral hemorrhage, causing death in some cases [8]. The current treatment for envenomation by Lonomia is administration of an antivenom produced against Lonomia obliqua Walker, 1855 by the Butantan Institute of Brazil [9], which has proven to be effective in response to envenomation by three species in Colombia: L. descimoni [10], L. orientoandesis [11] and L. casanarensis [11].…”

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. 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.
