The number of eggs that the insect is able to make varies according to the number of ovarioles, with the rate at which eggs develop being also influenced by ovariole design. In meroistic ovaries, the eggs-to-be divide repeatedly and most of the daughter cells become helper cells for a single oocyte in the cluster. In panoistic ovaries, each egg ...
T. penetrans eggs, on average, are 0.6 mm long, The larva will hatch from the egg within one to six days, assuming the environmental conditions (e.g., moisture, humidity, etc.) are favorable. [8] After hatching, the flea will progress through two instar phases. This is unique in that most fleas go through three.
Lifestages of a holometabolous insect ().Egg is not shown. Third, fourth, and fifth images depict different ages of pupae. Holometabolism, also called complete metamorphosis, is a form of insect development which includes four life stages: egg, larva, pupa, and imago (or adult).
[7]: 739–740 [20] When first laid, the eggs are white or cream-colored and oval-shaped, but right before hatching they become kidney-shaped and brown. [24] Each egg is approximately 1 mm (1 ⁄ 32 in) tall and 0.8 mm (1 ⁄ 32 in) wide. [21] Earwigs are among the few non-social insect species that show maternal care.
Lovebug eggs generally hatch after 2–4 days, depending on flight season. Once the eggs have hatched, the larvae start feeding on the decaying material around them, such as decaying plants on the soil and other organic material, and live and remain in the soil until they develop to the pupa stage.

Dragonflies are hemimetabolous insects; they do not have a pupal stage and undergo an incomplete metamorphosis with a series of nymphal stages from which the adult emerges. [61] Eggs laid inside plant tissues are usually shaped like grains of rice, while other eggs are the size of a pinhead, ellipsoidal, or nearly spherical.
For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape , or more specifically oviscape , the word scape ...
While the layout of internal genital ducts and openings of the female genitalia depends upon the taxonomic group that insect belongs to, the internal female reproductive system of all lepidopterans consists of paired ovaries and accessory glands which produce the yolks and shells of the eggs. Female insects have a system of receptacles and ...
