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.
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 ...
The wingspan of the blue morpho butterfly ranges from 7.5–20 cm (3.0–7.9 in). The entire blue morpho butterfly life cycle, from egg to adult is only 115 days. This butterfly undergoes metamorphosis from larva to butterfly. The larva eats plant leaves before spinning a chrysalis.
The chrysalis generally refers to a butterfly pupa although the term may be misleading as there are some moths whose pupae resembles a chrysalis, e.g.: the plume winged moths of the family Pterophoridae and some geometrid moths. A cocoon is a silk case that the larvae of moths, and sometimes other insects, spin around the pupa.
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.
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 odors also trigger the males to learn the location of the plant for future copulations. The butterfly's spatial memory is good enough to enable them to return regularly to roosts and mating sites. [24] A common problem among all butterflies is to avoid mating with other butterfly species. [25]
