Galls, growths of plant cells that are not normal plant organs, can be induced by a number of organisms. The most numerous as well as most beautiful and intriguing are those induced by insects. Two insect families are found only in plant galls: cynipidae (gall wasps) and cecidomyiidae (gall midges or gnats).

Tree galls are abnormal growths that occur on the leaves, trees, and branches. Tree galls can be caused by several things, including insect activity, bacteria, and fungi. Typically, galls are formed as a result of the tree growing this abnormal tissue in order to isolate the insect or pathogen.
More than 800 insect species create galls on oak twigs, and over 700 of them are wasps. These particular galls are so perfectly symmetrical that many observers figure they must be some kind of exotic fruit and not just a deformed oak leaf. Some leaf galls are not nearly as noticeable as the papery balls described here.
This disease is characterized by the formation of galls caused by insects or mites. Galls are abnormal plant growths that look like green or brown clusters formed on the branches. A tiny mite called eriophyid is responsible for infesting the ash tree. It causes male flowers to grow into small greenish round structures that turn.
Oak galls -- those curious growths that hang in trees or attach to the underside of leaves -- are well.
Although insects often damage dogwood trees, the damage is usually minor. If the tree is planted in full sun with limited water or under other stress, the damage can be serious. Most insect damage occurs on the trunk and branches of dogwoods. Commonly occurring insect pests of dogwood include the dogwood borer, dogwood club-gall midge, and scales.
Beneficial insects, including several species of parasitic wasps, help to suppress horned oak gall populations on many trees. Individual trees vary in resistance or susceptibility; often some are heavily infested while others nearby are nearly gall-free.
— a strange growth known as galls frequently appear on plants as a result of feeding activity of insects. Even though they are unsightly, the good news is that galls normally do not cause lasting damage to plants, according to kelly mcgowan, horticulture educator with university of missouri extension.
These phases of cecidogenesis parallel those of many modern insect galls (meyer, 1987). The morphology, association with a particular host plant, and physical location on the plant organ strongly suggest that these ovoid structures are insect galls, herein described as ovofoligallites padgetti, and permit attribution to a modern gall type.

The are galls, growths on plants that are usually caused by insects. According to the university of minnesota: “galls are abnormal plant growths caused by various organisms (insects, mites, nematodes, fungi, bacteria, and viruses). This publication will deal with galls caused by the feeding or egg- laying activity of insects and mites.
Other insects that can sting are: yellow jackets, hornets, wasps, fire ants, honeybees. These insects are very different but all make venom that causes inflammation when inserted through the sting. Yellow jackets-ground-dwelling insects, nests are concealed in the ground or behind siding or retaining walls.
) the transformative changes an insect passes through as it moves from one stage of its life cycle to the next is called metamorphosis. While about 10 percent of insects undergo what's known as incomplete metamorphosis, the majority of insect species experience some dramatic changes as they mature.
Galls are good nutrient sources, so other insects may feed on them or use the gall for shelter. Some of these insects can also kill some or all of the gall-makers. The gall invaders may include gall wasps that cannot form their own galls, gall midges, clearwing borers, longhorned beetles, metallic wood-boring beetles, weevils, ants, and others.

The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice. It is remarkable, scientists say, because the bug’s physical characteristics – from the bold banding pattern on its legs to the internal features of its genitalia – are clearly visible and well-preserved.
Galls differ widely in size, shape, and structure, with each gall former inducing galls with distinct characteristics specific to that insect species. Tissue differentiation in insect galls reveals all gradations of complexity, and in most galls there are fundamental histological differences from the normal organ.
These growths may be the result of fungi, bacteria, nematodes, or mites, but insects are the prime cause. Gall-forming insects include aphids, phylloxerans, psyllids, midges (gall gnats) and cynipid wasps (gall wasps).
Galls are abnormal growths of plant tissue caused by a wound, infection by a microorganism, or the feeding and egg-laying activity of certain insects and mites. Although galls are conspicuous and unattractive, they rarely cause serious damage.
Approximately 1,100 morphospecies of gall-inducing insects have been found thus far in costa rica. Seventy percent of these are cecidomyiidae, a group whose true species richness is potentially huge; other prominent groups include psylloidea, hymenoptera (5 families), and lepidoptera (14 families).
By studying diverse gall-inducing insects we have discovered that insects with needle-like sucking mouthparts may also induce a nutritive tissue, whose nutrients are indirectly harvested as the gall-inducing insects feeds on adjacent vascular tissues. Activity of carbohydrate-related enzymes across diverse galls corroborates this hypothesis.
They had hollowed out collarswith the galls themselves being conical shapes about 4 mms tall. Br at least three other leaves showed similar galls but they were dry and partially destroyed.
Galls on trees are often a sign of insect activity and may not be cause for concern. However, they could be an indication of disease such as cedar rusts leaf spots can be caused by overly wet weather and fungi and like galls, won’t necessarily harm your trees.
Insect-induced galls are intricately patterned homes that pro-vide insects with protection from environmental vicissitude and from some predators and parasites. 5–7 galls are also resource sinks, drawing nutrients from distant plant organs and providing insects with abundant food.
Most galls are formed by three kinds of insects or mites: gall wasps, gall midges, and gall mites. Other less common gall producing insects are aphids, psyllids, and gall flies. Since most galls seem to do no permanent damage to their host plants, limited research has been done on the biology or control.

A gall wasp is a flying insect of the same family as the common wasp. It has the particularity of requiring a specific host plant as part of its reproductive cycle. A particular gall wasp species usually only infects a single specific plant species or genus. For example, the citrus gall wasp will only infect citrus trees.
Galls caused by tiny wasp larvae are causing leaves on oak trees from rolla and lake of the ozarks to springfield and table rock lake to turn brown.
Some of these gall-forming insects are host specific, like the hackberry nipple gall or the maple bladder gall on silver maples. Oaks likely win the contest when it comes to hosting insects that create galls with more than 700 gall forming insects using oaks.
Each species of insect that makes galls stimulates their host tree to produce a unique type of gall to protect their growing young. The yellow wig, red cone, urchin, crystalline, and disc gall wasps have galls that allude to their names.
The gall is a growth caused by the wasp larva that then provides a food source for the growing larva.

Insects and mites (hereafter ‘insects’) and the galls they induce are known presently far more than before1–4. The discovery of ‘samurai’ aphids and their unique behaviour among the gall-inducing aphidoidea by shigéyûki aôki was a milestone event5,6 that stimulated similar explorations in other gall-inducing insect groups7.
For some unknown reason, willows are extremely susceptible to gall induction and growth manipulation - in fact, salix is one of the plant genera with the highest known numbers of associated galler species. Willow galls are induced by cecidomyiid midges, sawflies, and mites.
These structures, called galls, have fascinated biologists for centuries. They’re crafted by a variety of insects, including some species of aphids, mites, and wasps. And they take on innumerable forms, each specific in shape and size to the insect species that’s created it – from knobs to cone-shaped protrusions to long, thin spikes.
