Illustration of life stages of pūriri moth (1a-1c) from "An elementary manual of New Zealand entomology; being an introduction to the study of our native insects", George Vernon Hudson (1892). The larva emerges at night to feed on callus tissue around the entrance to the burrow, where it is hidden under a camouflaged web of silk (often ...
Manduca quinquemaculata, the five-spotted hawkmoth, is a brown and gray hawk moth of the family Sphingidae.The caterpillar, often referred to as the tomato hornworm, can be a major pest in gardens; they get their name from a dark projection on their posterior end and their use of tomatoes as host plants.
Some caterpillars, like early instars of the tomato hornworm and tobacco hornworm, have long "whip-like" organs attached to the ends of their body. The caterpillar wiggles these organs to frighten away flies and predatory wasps. [18] Some caterpillars can evade predators by using a silk line and dropping off from branches when disturbed.
The following description of the tent caterpillar life cycle is based on that of the eastern tent caterpillar, the best-known species. The details of the life histories of other species vary to a small extent. Tent caterpillars hatch from their eggs in the early spring at the time the leaves of their host trees are just unfolding.
Throughout its life cycle, an individual makes several shelters, possibly for protection from predators; the larvae emerge to feed at night. The first of these is flimsy and temporary, but in the third instar, they build a permanent nest. Once the permanent nest is built, the caterpillars become foragers, staying in the vicinity of the nest.
Gynaephora groenlandica, the Arctic woolly bear moth, is an erebid moth native to the High Arctic in the Canadian archipelago, Greenland and Wrangel Island in Russia. [2] [4] It is known for its slow rate of development, as its full caterpillar life cycle may extend up to 7 years, with moulting occurring each spring. [5]
Throughout its life as a larva the saddleback caterpillar will go through a series of growths and molts. During the period between each molt the larva is regarded as an instar to indicate its progression into adulthood. The first instar: Caterpillar larvae vary in size and are capable of being between 1.5-2.0mm in length. [3]
The ground lackey larva is a tent caterpillar. which makes a new tent with each moult. Fully-grown caterpillars are fast walkers. [1] The pupa is not cocooned. [3] Adults fly from June to August, depending on the location. The length of the forewings is 13–16 mm for males and 17–21 mm for females. They fly at night. [2]
