Some species are predatory, but most of them feed on pollen and the chloroplasts harvested from the outer layer of plant epidermal and mesophyll cells. They prefer tender parts of the plant, such as buds, flowers and new leaves. [38] [39] Besides feeding on plant tissues, the common blossom thrips feeds on pollen grains and on the eggs of mites ...
Orius insidiosus, the "insidious flower bug", for example, feeds on the eggs of the corn earworm (Helicoverpa zea). Orius insidiosus is often released in greenhouses against mites and thrips. [6] Eggs are laid in plant material and hatch in approximately 3 to 5 days. Nymphs require at least 20 days to progress through five instars.
Stalked eggs of unknown species, Mainzer Sand (Rhineland-Palatinate, Germany) Larva of a species in the Chrysoperla carnea group feeding on an aphid. Eggs are deposited at night, singly or in small groups; one female produces some 100–200 eggs. Eggs are placed on plants, usually where aphids are present nearby in numbers. Each egg is hung on ...
Linaria vulgaris, the common toadflax, [1] [2] yellow toadflax or butter-and-eggs, [3] is a species of flowering plant in the family Plantaginaceae, native to Europe, Siberia and Central Asia. [4] It has also been introduced and is now common in North America.
[31] [50] [67] The female uses its ovipositor to drill into plant material to lay her eggs (though the family Orussoidea lay their eggs in other insects). Plant-eating sawflies most commonly are associated with leafy material but some specialize on wood, and the ovipositors of these species (such as the family Siricidae) are specially adapted ...
The adult caddisfly is a medium-sized insect with membranous, hairy wings, which are held in a tent-wise fashion when the insect is at rest. The antennae are fairly long and threadlike, the mouthparts are reduced in size and the legs have five tarsi (lower leg joints). [19] Adults are nocturnal and are attracted to light.
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.

Dryas iulia eggs tend to be a light yellow color when laid, which turns to a darker orange or brown shade before hatching. Each of the butterfly's eggs are separately laid onto new leaf tendrils of its host plant, usually the passionflower vine. [8] The egg of the butterfly measures about 1.2 mm in height and 1.0 mm in diameter.
