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 ...
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 ...
Primary consumers are herbivores, feeding on plants or algae. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants). There are certain primary consumers that are called specialists because they only eat one type of producers.
Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.
Gonimbrasia belina is a species of emperor moth which is native to the warmer parts of southern Africa.Its large edible caterpillar, known as the mopane worm, madora, amacimbi “pigeon moth”, masonja or Seboko sa Mongana, feeds primarily but not exclusively on mopane tree leaves.
The caterpillars eat from several host plants. [6] Caterpillars begin as yellow with black stripes, but become blue green over time. Once they are blue green, they develop four red and one yellow protuberances. These caterpillars go through several instars or skin shedding, and usually after the fifth shedding the caterpillar is ready to form a ...
In specific local subpopulations (studied in Wisconsin, Ohio, and Florida), it was found that eastern giant swallowtail caterpillars do better on their local host plant than on other giant swallowtail host plants. The local host caused the larva to develop faster than other plants that were also edible to the larva.
The zebra caterpillar is the larva of an American noctuid moth (Melanchra picta) that feeds on cabbages, beets and other cultivated plants. The head, thorax, and forewings of adults are chestnut- or reddish-brown, usually with purplish brown mottling on the wings. The whitish hind wings have pale brown margins. The abdomen is light gray.
