Larva Chrysalis. Males actively patrol for females. [2] Females lay their pale-green or cream-colored eggs singly on host plant leaves and stems. The larva eats the leaves, flowers, and stems of the food plant. [2] [11] The larva is red with black subdorsal and spiracular stripes infused with white spotting. In many individuals, the white is ...
By small contractions of the muscles it begins to shed its skin and head revealing a soft pinkish tan form. Quickly the soft form hardens and becomes grayish brown. The chrysalis stays in this form for eleven to twenty-one days. After that period of time, a small crack begins to form at the tip of the chrysalis revealing the butterfly's head.
This butterfly undergoes metamorphosis from larva to butterfly. The larva eats plant leaves before spinning a chrysalis. Flower nectar, which is available later in the year, is used by the butterfly. A recent study also discovered that during transformation, the butterfly substantially reduces its body weight and body fat. [6]
Polygonia interrogationis, commonly called the question mark butterfly, is a North American nymphalid butterfly. It lives in wooded areas, city parks, generally in areas with a combination of trees and open space. The color and textured appearance of the underside of its wings combine to provide camouflage that resembles a dead leaf. The adult ...
The dainty sulphur will migrate south to spend the winter because it is unable to survive the cold. If day length is short when it is a larva, the dainty sulphur produces a winter phenotype upon forming its chrysalis which will then produce a butterfly with three times the usual number of dark scales. This allows it to absorb solar heat more ...
After a period of feeding and growth, during which it moults one last time, the caterpillar is full size and ready to pupate. The chrysalis stage is formed among the leaf litter, and lasts just 10–14 days. The adult butterfly flies between late April and June, and is one of the earliest fritillaries to emerge.
The caterpillar grows to around 5 cm in length before forming a chrysalis, which is brown or green and about 3 cm long. [4] The anise swallowtail pupa looks like a thick branch coming off of the larval host plant. The top of the pupa extends slightly from the plant, held by strong silk. This is where the adult butterfly emerges. [citation needed]
The caterpillar will form a chrysalis that is pointed at both ends and humped in the middle. The chrysalis will be either yellow or green with pink or green stripes. From the chrysalis comes a medium-sized butterfly (55–70 mm (2.2–2.8 in)) with fairly elongated but not angled wings.
