Spores of O. elektroscirrha are ingested by the caterpillars when they eat their egg chorion (shell) after they hatch, and when they feed from infected milkweed. Once the parasite has entered the host's gut , the spores open and emerging sporozoites penetrate the gut wall and migrate to the hypoderm (the layer of cells that secrete the larva's ...
Plants contain toxins which protect them from herbivores, but some caterpillars have evolved countermeasures which enable them to eat the leaves of such toxic plants. In addition to being unaffected by the poison, the caterpillars sequester it in their body, making them highly toxic to predators. The chemicals are also carried on into the adult ...
Butterflies need specific plants, called host plants, where they can lay their eggs and caterpillars hatch. Not all caterpillars will become butterflies, of course, because some are eaten by birds.
The tree in which a female deposits the eggs is where the larvae will choose to feed. The most common host plants that caterpillars feed on are leaves from stonefruit trees. However, larvae will feed on many other types of tree foliage. Adult moths do not eat and live for 1–4 days. [7]
A tail-like spine protruding from the back of the body is a typical for sphingid moth caterpillars, known as “hornworms”. [2] This horn, which may sometimes be yellow and have a black tip, is not a stinger, and the caterpillars are not harmful to humans. [7] The larvae can also sometimes be lime green and black.
Certain caterpillars eat plants that are toxic to both themselves and the parasite to cure themselves. [24] Drosophila melanogaster larvae also self-medicate with ethanol to treat parasitism. [25] D. melanogaster females lay their eggs in food containing toxic amounts of alcohol if they detect parasitoid wasps nearby. The alcohol protects them ...
Caterpillars from species in the genus Triodes feed on poisonous plants, and accumulate the poisons in their body making them poisonous to predators like birds. Whilst most species of caterpillars feed on leaves, some burrow into the soil feeding on roots, some bore into trees eating the wood, and caterpillars of the moth Argyrotoxa pompica ...
After mating, females lay eggs on all parts of the host plant, oftenmost on the uppersides of leaves. The caterpillars eat all parts of the plant; host species include Pigweed (Chenopodium album), saltbush species , and others in the goosefoot family (Chenopodiaceae). Adult imagos appear in July–September in the north, while it appears year ...
