Lonomia obliqua is a species of saturniid moth ("giant silk moth") from South America. [1] It is famous for its larval form, rather than the adult moth, primarily because of the caterpillar's defense mechanism, urticating bristles that inject a potentially deadly venom.
Lonomia sp.. The genus Lonomia is a moderate-sized group of fairly cryptic saturniid moths from South America, famous not for the adults, but for their highly venomous caterpillars, which are responsible for a few deaths each year, [1] especially in southern Brazil, and the subject of hundreds of published medical studies.
The gypsy moth caterpillar has been reported to produce a poison ivy like rash when some people come into contact with the hairs of the larvae (caterpillar) stage. The contact can be direct or even indirect, if the small hairs are carried by the wind and onto the skin or clothing of a person.
Effects from the poisonous bristles under their fur have been compared with a wasp or jellyfish sting. The Initial symptom of being stung by a puss caterpillar is usually just a painful skin ...
Lonomia achelous, the Brazilian caterpillar or giant silkworm moth caterpillar, [1] is a venomous caterpillar endemic to South America. The species was first described by Pieter Cramer in 1777. Description and behavior
These toxic species, such as the cinnabar moth (Tyria jacobaeae) and monarch (Danaus plexippus) caterpillars, usually advertise themselves with the danger colors of red, yellow and black, often in bright stripes (see aposematism). Any predator that attempts to eat a caterpillar with an aggressive defense mechanism will learn and avoid future ...

The trails they follow are all pheromone based. The pheromones are deposited by caterpillars as they move to distant feed sites. These trails facilitate the re-aggregation of the group at the new feeding location and help prevent separation. [8] At dawn, caterpillars will follow a pheromone trail to the original central place site to form ...
