The larvae that emerge are marked with several stripes but can be quite variable in overall color. Dark forms are common but red and green larvae may also be seen.
Larvae
The larva measures about 1.7 mm in length at hatch. It is light cream colored with a black head and caudal (rear) shield. The head and shield become lighter as the larva matures until they are pale brown in the mature fifth-instar stage.
Larvae: This is the white grub stage that is so familiar in lawns. Japanese beetle larvae have a V-shaped series of bristles on their raster (the underside of the tip of the abdomen.) Grubs will grow in length as they feed and mature.
Trap larvae. After larvae have finished feeding on the fruit, they wander to flaps of bark or other protected sites to pupate.
Larvae (of Adult May or June beetles), are white, C-shaped grubs with distinct, brown heads and three pairs of legs near the front end. Larvae or grubs about 1 to 1.
Larvae can be captured before maturation by placing a half-inch thick slice of potato on the soil surface.
Larvae are produced from the eggs that will dig their way back near the surface in August. Japanese beetle larva will feed on the roots of turf grass.
* Larvae (Caterpillar) Host Plants
The typical garden is not likely to accidentally have plants that host the larvae of most butterflies.
The larvae of Codling Moth Cydia pomonella that infest apples, is an unwanted pest in this favourite crop. It is essential that fallen fruit are not left to lie and rot on the ground if you are serious about controlling this pest.
The larvae of the onion fly live in the soil around the roots of onions. These larvae are white and fat and they can do considerable damage to the crop. Carrot flies lay their eggs at the base of carrots, parsley, parsnips and celery.
Grubs are larvae that will grow into beetles. They often grow beneath your lawn, and can cause rings of dead grass to form. When the grubs mature, the adult insects can then move on to eat and kill your plants. ... Read More ...

Larva (pl. larvae)-The immature form of insect that develops through the process of complete metamorphosis, including egg, several larval stages, pupa, and adult. In mites, the first-stage immature is also called a larva.
The larvae of several species of moths that pupate just beneath the surface of the soil. While in the larval stage they emerge at night and "cut down" seedlings, then devour them, leaving no evidence beyond the severed stem.
Larvae of the carrot root fly are known to eat into the carrot's flesh, leaving tunnels that cause the vegetable to rot.
Because butterfly larvae eat the host plants they hatch on, your plants can get a bit raggedy.

Slugs, cabbage root fly, flea beetles, weevils and other soil pests
Lacewing and larvae ...
Damage: Grubs (larvae) feed on grass roots, resulting in a wilted, stunted and stressed lawn. A gentle tug reveals the roots have been eaten. Skunks and raccoons often dig up lawns to look for the tasty grubs.
The eggs are usually laid on an infested plant so that the larvae can feed on the mealy bugs as well.
Green lacewings larvae (Aphid Lions) will eat spider mites, thrips, leafhoppers, whiteflies and caterpillar eggs.
The ladybugs emerge as larvae, feed for two or three weeks, then, attaching themselves to a leaf or stem, pupate (the structure of the larval body rearranging itself completely).
The larvae have even more problems to deal with, from birds to wasps and other bugs, to spiders. They also have to fend off disease problems, and avoid pesticide sprays.
You can spray the base of the plant with rotenone, pyrethrins or BTK to kill the larvae before they enter the vines.
Larvae that remained dormant and hibernated during the winter in spring turn into adult codling moths. These adults lay their eggs and the larvae that emerge will burrow into apples.
The minute, white, worm-like larvae slither through the upper surface of the medium, destroying vital rhizoids. Adult fungus gnats have light-colored wings and adult shore flies have dark ones.
Chewing insects: This group includes caterpillars and beetle larvae, such as the Colorado potato beetle, cabbage worms, and tomato hornworms. These pests can be voracious feeders that chomp down entire leaves and completely defoliate plants.
Larvae have six legs and a ridged skin that makes them look whitish. Adult mites are only .08 inch long and larvae are 1/2 that size.
When wishing to rear queens, take a frame from the hive which contains your pure Italian queen, and be sure that the comb has in it eggs, young larvae, and hatching bees.
Hornbeams are susceptible to damage by gypsy moth larvae, which eat the leaves in midsummer. However, not every caterpillar is a pest. American hornbeams are important food for the larvae of tiger swallowtail and other butterflies.
Nematodes are recommended for use whenever larvae or grubs of insects targeted for control are present during the spring and fall months.
Q: How long does it take mosquito larvae to develop into adults?
A: It takes as few as four days for some species of mosquito larvae to develop into adults.
Curculio The tiny adult beetle lays it eggs on the fruit and the larvae tunnel into the apple. When the larvae start feeding, the fruit drops and the larvae crawl out and burrow into the soil.
tenebrionis, which is effective against Colorado potato beetle and elm leaf beetle larvae; Bt var. kurstaki, which is used to target caterpillars (many of which are important farm and garden pests); Bt var.
Spotted asparagus beetles do lay eggs on asparagus, and the adults and larvae do feed on asparagus (often on the berries), but they do less damage than the common asparagus beetle, although the life cycles are the same.
Cane borers are tiny caterpillar-like larvae that enter rose canes through tiny wounds and pruned stems, and then proceed to set up housekeeping. On occasion, they may enter the by actively boring into the cases.
The developing larvae are cream colored and grow up to 22 millimeters long. They bore their way through the bark into the cambial region and feed on phloem cells and outer sapwood for several weeks.

The maggot larvae begin to feed in the outer scales of the bulb and eventually work their way into the interior of the bulb. The foliage of infested plants may become wilted, yellow and distorted and the plant will eventually die.

You can order parasitic gall-midges, larvae that hatch and eat aphids without chewing on anything else in your garden.
As the host goes through its various stages of development, the parasite egg divides and produces several individual larvae. When the host dies, the larvae pupate within it, to emerge later as adult wasps.
Larva - An immature stage through which some types of insects must pass before developing into adults. Caterpillars are the larvae of moths and butterflies, and grubs are the larvae of beetles. Larvae are typically wormlike in appearance.
