The caterpillars molt their old skin in each instar, and each instar is unique. They have been observed as far south as Mexico and as far north as Ontario, although these sightings are inconsistent. Battus philenor is another California endemic (family Papilionidae, order Lepidoptera). The Aristolochea contain the poisonous aristolochic acid, a renal toxin and probable carcinogen. The males’ iridescent hind wings are also believed to be involved in attracting females. The larvae hatch after a few weeks and immediately eat the remnants of the egg from which they emerged. This butterfly is black with iridescent-blue hindwings. Female eastern tiger swallowtail butterflies ( Papilio glaucus ) , female eastern black swallowtail butterflies ( Papilio polyxenes ), promothea silkmoth males (Callosamia promethea)[17] and the spicebush swallowtail (Papilio troilus) use the swallowtail as a template for mimicry.

Limenitis arthemis, the red-spotted purple or white admiral, is a North American butterfly species in the cosmopolitan genus Limenitis.It has been studied for its evolution of mimicry, and for the several stable hybrid wing patterns within this nominal species; it is one of the most dramatic examples of hybridization between non-mimetic and mimetic populations. "It derives its protection from the toxic aristolochic acids produced by the host, which it sequesters; females even pass these along to the eggs, which are also protected (and are brick red, laid in bunches of up to 20, and quite conspicuous).

The pipevine swallowtail butterfly, Battus philenor, is a relatively small black swallowtail with gorgeous, iridescent blue scaling. To accomplish this, the female butterfly lays unfertilized eggs that are fertilized and coated protectively during the laying process. Males may also use sodium taken up from mud as a nuptial gift during mating. The caterpillars of the Pipevine Swallowtail feed on the poisonous host plant, Aristolochia, also known as the pipevine, Dutchman's pipe or birthwort. The dorsal wings of an adult male are black with vibrant blue iridescence on the hind wings.

The woolly Dutchman’s pipevine is one of several plants in the. Pupation begins when the larva releases silk to form a support structure so that the chrysalis can hang safely. They are mostly seen during the spring and the summer months in sunlit meadows and fields. Once it is time to form a pupa, the caterpillar stops eating and disposes of any undigested food. The Pipevine Swallowtail is a butterfly, but can also be considered a moth. This takes longer than laying already-fertilized eggs and means that the mother is exposed to danger for a longer time while she remains motionless, but evolution suggests that the benefit to the resulting caterpillar is greater than the danger to the mother. Prior to emerging as an adult, the wing markings of the butterfly can be seen through the chrysalis. Telescope Accessories: What Do You Really Need?
