Once the larval stage is complete, the caterpillar enters the pupal stage, forming a chrysalis–a hard shell used for protection while it develops into a butterfly. The pupal stage can last from a couple of weeks to several months, depending on environmental conditions. The caterpillar undergoes metamorphosis and emerges a butterfly. In the ...
The larvae feed on species of plants belonging to the Papaveraceae and Crassulaceae families, and like the other swallowtail butterfly larvae, possess an osmeterium. [1] Unlike most butterflies that have exposed pupae, they pupate inside a loose silken cocoon.
Myrtle's silverspot (Speyeria zerene myrtleae) is a medium-sized butterfly in the brush foot family (Nymphalidae), an endangered subspecies of the zerene fritillary.It is endemic to California, where it is known from only about four locations just north of the San Francisco Bay Area, including two at Point Reyes National Seashore.
Caterpillars, are "characteristic polypod larvae with cylindrical bodies, short thoracic legs and abdominal prolegs (pseudopods)". [63] They have a toughened ( sclerotised ) head capsule, mandibles (mouthparts) for chewing, and a soft tubular, segmented body, that may have hair-like or other projections, three pairs of true legs, and additional ...
Papilio aegeus, the orchard swallowtail butterfly or large citrus butterfly is a species of butterfly from the family Papilionidae, that is found in eastern Australia and Papua New Guinea. The larvae of this species are sometimes considered a pest, due to their feeding on citrus leaves in suburban gardens.
The small tortoiseshell butterfly is severely affected by droughts. During periods of drought, the butterfly experiences a vastly reduced reproductive rate. The drought directly affects the Urtica leaves; the higher the nitrogen and water level in the leaves, the more rapid the growth of the larvae. During a drought, both of these levels drop ...
The small larvae hatch in late September and into October. Immediately after hatching, the tiny larvae seek protective covering in the leaf litter and overwinter there. At this stage the larvae delay development over the winter months and this is known as larval diapause (Kopper et al. 2001). Once spring arrives, the larvae emerge and begin ...
The eastern giant swallowtail (Papilio cresphontes) is the largest butterfly in North America. [2] It is abundant through many parts of eastern North America; populations from western North America and down into Panama are now (as of 2014) considered to belong to a different species, Papilio rumiko.
