Coreidae
Leaf-Footed Bugs
Leaf-footed Bugs get their common name from the leaf-like extension found on the hind legs of many species.

(Family: Aleyrodidae)
Whiteflies (Family Aleyrodidae). Despite their name, whiteflies are not actually true flies but rather closely related to aphids and mealybugs.
(Family: Noctuidae)
These caterpillars are the larvae of some moths in the family Noctuidae. They get their name from their behavior of cutting small plants at the base of the stem. Since there are so many species, they come in a variety of colors and patterns, so damage is the best way to identify them.
(Family: Tetranychidae)
Spider mites are not insects but arachnids (think spiders, scorpions, etc.) that damage plant cells by piercing them to feed. These are VERY SMALL and are often not noticed until their population has exploded.
(Family: Pentatomidae)
Like other pest Hemipterans, these insects feed on plant sap with their piercing-sucking mouthparts. They can greatly weaken plants especially if the population is large.
(Family Aphididae)
This is one bug I think most people can identify immediately.
(Species: Helicoverpa zea)
This moth species belongs to the dreaded family of moths called Noctuidae. Within this family, you can find other agricultural pests often referred to as cutworms.
(Order Thysanoptera)
A thrips (no, that’s not a typo—there’s no such thing as a thrip!) is a bizarre, minute insect. They are typically less than 1 mm long with slender bodies, fringed wings and weird lopsided mouth parts.
Though the larvae are known as wireworms, adult insects in the family Elateridae are known as click beetles.
(Family: Diaspididae)
Armored scale insects are known as one of the more frustrating pests and often don’t look like insects at all. These tiny sap-suckers create protective, waterproof coverings to fend off the elements and predators.
Leaf-mining flies
(Genus: Liriomyza)
The larva create tunnels in the mesophyll, leaving the epidermis intact. This will resemble light colored “squiggles” on the leaves.
(Family: Pseudococcidae)
These unarmored scale insects damage tomatoes by feeding on their plant saps and secreting a sweet concoction known as “honeydew,” which encourages the growth of sooty molds. They also are known to transmit diseases.
Green June beetles are well known and hated by many gardeners; their other aliases are June bugs or June beetles. Though considered pests in both larval and adult stages, the grubs are known to be more destructive in most settings.
(Family: Chrysomelidae)
These little cuties are unfortunately a huge issue for many tomato growers.
(Family: Sphingidae)
These large caterpillars often reach 5 inches in length and are most easily identified by the “horn” protruding from the tip of their abdomen.
(Family: Coccidae)
Soft Scale is a very diverse family of insects so there is often exceptions in physical appearance. Though they may not look like insects, these Hemipterans are related to aphids, whiteflies, and mealybugs.
Loopers are easily identified in their larval stage because they crawl by arching their backs, creating a “loop.”
(Suborder: Caelifera, grasshoppers and relatives)
Grasshoopers generally have wings and large back hopping legs. You can differentiate them from crickets by looking at their antennae—cricket antennae are usually long, since they’re nocturnal insects, so they use those long “feelers” to help with walking around.
