The ruby-throated hummingbird (Archilochus colubris) is a species of hummingbird that generally spends the winter in Central America and migrates to Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America.

Psocoptera are an order of insects that are commonly known as booklice, barklice or barkflies.[1] They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipteroids.[2] Their name originates from the Greek word ψῶχος, psokhosmeaning gnawed or rubbed and πτερά, ptera meaning wings.[3] There are more than 5,500 species in 41 families in three suborders. Many of these species have only been described in recent years.[4]

Galls or cecidia are a kind of swelling growth on the external tissues of plants or animals. Plant galls are abnormal outgrowths[1] of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from fungi and bacteria, to insects and mites. Plant galls are often highly organized structures and because of this the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology.

A dragonfly is an insect belonging to the order Odonata, infraorder Anisoptera (from Greekἄνισος anisos, “uneven” and πτερόν pteron, “wing”, because the hindwing is broader than the forewing). Adult dragonflies are characterized by large, multifaceted eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Dragonflies can be mistaken for the related group, damselflies (Zygoptera), which are similar in structure, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold the wings folded at rest, along or above the abdomen. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly’s compound eyes have nearly 24,000 ommatidia each.
Odonata is an order of carnivorous insects, encompassing the dragonflies (Anisoptera) and the damselflies (Zygoptera). The Odonata form a clade, which has existed since the Triassic.
Dragonflies are generally larger, and perch with their wings held out to the sides; damselflies have slender bodies, and hold their wings over the body at rest.
