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 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
Silkworms produce silk when undergoing larval to adult metamorphosis. Raspy crickets produce silk to form nests. Honeybee and bumblebee larvae produce silk to strengthen the wax cells in which they pupate. [1] Bulldog ants spin cocoons to protect themselves during pupation. [1] Weaver ants use silk to connect leaves together to make communal ...
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 English epithet is derived from the caterpillar's defense mechanism, which consists of an audible squeaking akin to that of a squeak toy. The sound is produced through rapid bodily contraction, which forces air through the spiracles of the larva. The pupae of R. fugax are separately known as ヤマカマス (yama-kamasu).
Ants imbibe the secretion produced by the nectary organ, and tentacle organs function in chemical communication between caterpillars and ants. The sounds produced by lycaenid caterpillars are similar to those produced by ants, [5] [6] an interesting cross species convergence which facilitates caterpillar-ant communication. Lycaenid caterpillars ...
Samia ricini, the eri silkmoth, is a species of insect, a member of the family Saturniidae which includes the giant silk moths. This moth is a domestic polyhybrid that has been bred for centuries due to the silk it makes.
When the eggs hatch, small yellow caterpillars emerge. As the caterpillars age, they molt five times (the fifth being into a pupa). Each instar is slightly different, but on their fifth and final instar, they become bright green with silver spots on their sides. They feed heavily on their host plant and can grow up to 3–4 inches long.
