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.
The African death's-head hawkmoth (Acherontia atropos) is the largest moth in the British Isles (though not in Africa), with a wingspan of 12 cm (5 in); it is a powerful flier, having sometimes been found on ships far from land. The forewings are a mottled dark brown and pale brown, and the hind wings are orangey-buff with two narrow dark bands ...
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.
As caterpillars, they tend to feed on a wide range of host plants. This includes oak, apple, birch, willow, hackberry, cherry and coniferous trees such as fir and spruce.
As a chrysalis, some of the caterpillar's organs dissolve. Groups of special cells divide and multiply to form wings and other adult body parts. What's inside a caterpillar cocoon
The Sphingidae are a family of moths commonly called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as hornworms. It includes about 1,450 species. [1] It is best represented in the tropics, but species are found in every region. [2]
Some caterpillars even bite the female wasps that approach them. Some insects secrete poisonous compounds that kill or drive away the parasitoid. Ants that are in a symbiotic relationship with caterpillars, aphids or scale insects may protect them from attack by wasps. [18] [19] Parasitoid wasps are vulnerable to hyperparasitoid wasps.
Sixth-instar caterpillars below the threshold size for pupation at the end of the fifth instar are killed through parasite emergence. Upon reaching the fifth instar, the caterpillar will enter a wandering stage, as is typical, but will not progress further and will not form a cocoon. The onset of the wandering stage is temporally delayed as ...
