For example, in Nemoria arizonaria caterpillars, the cryptic pattern changes according to season and is triggered by dietary cues. In the spring, the first brood of caterpillars resembles oak catkins, or flowers. By the summer when the catkins have fallen, the caterpillars discreetly mimic oak twigs. [31]
Monarch caterpillars deter predators by incorporating these chemical compounds into their bodies, where the toxins remain throughout the insect's lifetime. [50] Although monarch caterpillars will feed on butterfly weed (A. tuberosa) in butterfly gardens, it is typically not a heavily used host plant for the species. [51]

Butterfly larvae, or caterpillars, consume plant leaves and spend practically all of their time searching for and eating food. Although most caterpillars are herbivorous, a few species are predators : Spalgis epius eats scale insects , [ 48 ] while lycaenids such as Liphyra brassolis are myrmecophilous , eating ant larvae.
The caterpillar undergoes metamorphosis and emerges a butterfly. In the adult stage, within a few hours of emerging, the butterfly's wings dry and expand, allowing it to fly. During this stage, the butterfly focuses on reproduction and finding a mate. Once the female is fertilized, the cycle begins again.

[5] Caterpillars are often black or red, and feed on compatible plants of the genus Aristolochia. They are known for sequestering acids from the plants they feed on in order to defend themselves from ...
Biological insecticides, such as Bacillus thuringiensis, as well as chemical insecticides, are used to protect trees against larvae. [4] Methionine, an essential amino acid in humans, has also been found to be an effective killer of caterpillars, with possible use as a nontoxic pesticide against eastern giant swallowtail larvae.
