The eggs, larvae, pupae, and adults of certain insects have been eaten by humans from prehistoric times to the present day. [4] Around 3,000 ethnic groups practice entomophagy. [5] Human insect-eating is common to cultures in most parts of the world, including Central and South America, Africa, Asia, Australia, and New Zealand. Eighty percent ...
The caterpillar has been reported to cause irritation to humans. [1] [2] [3] Like all limacodids, the legs are shortened and the prolegs are reduced to suction cups. The "arms" or tubercles can fall off without harming the caterpillar, aiding the larva in defense. The larvae are 1.5–2.5 centimetres (0.59–0.98 in) in length. [1] [2]
Its consumption of toxic plants makes it distasteful to most predators. An exception is the smooth-billed ani (Crotophaga ani), which tears the caterpillar apart to eat it, avoiding the gut containing the plant material. The caterpillar is also coated in barbed urticating hairs, which stick deeply in skin and cause irritation. If caught, the ...
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 ...
The later-instar caterpillars are seen between July and October. [4] They feed in groups of about 100 or so in the early instars, [4] skeletonizing leaves. Older larvae are solitary. They grow up to 4.5 centimeters long before pupating. Larvae primarily feed on hickory, pecan, and walnuts, but will also eat ash, elm, oak, willow, and other ...
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 ...

As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. [3] With a wide geographic range throughout Central and North America, H. lineata is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults. [4] [5]
