Giant Centipede
A long, fast-moving, many-legged predator with a hardened segmented body and a pair of venom-injecting claws behind the head that it uses to overpower prey far larger than itself.
myriapod
Common True Katydid
A living leaf that spends its life high in the treetops, the common true katydid is far more often heard than seen, producing the loud, rasping "katy-did, katy-didn't" chorus that fills eastern summer nights.
grasshopper-cricket
American Copper
A small, bright orange-and-black butterfly with fiery copper-colored forewings and dusky gray hindwings edged in orange, commonly seen darting low over weedy fields and vacant lots.
butterfly
Drain Fly
A tiny, fuzzy gray-tan fly with broad, moth-like wings held tent-fashion over its body, often seen resting motionless on bathroom walls near drains.
fly
Blister Beetle
An elongated, soft-bodied beetle with a distinctly narrow neck, often seen feeding in small groups on flowers, and known for releasing a defensive chemical from its leg joints when disturbed.
beetle
Squash Bee
A robust, early-rising solitary bee specialized in visiting squash, pumpkin, and gourd flowers, often seen foraging in the cool early morning hours before many other pollinators are active.
bee
Damselfly
A slender, delicate relative of the dragonfly with widely spaced eyes and slim wings that fold together over its back at rest, often seen fluttering weakly among reeds and grasses at the water's edge.
dragonfly
Blue Bottle Fly
A robust fly with a glossy, metallic blue-black body and a loud buzzing flight, commonly seen around outdoor waste and occasionally indoors, easily recognized by its shiny coloring and bristly frame.
fly
Dragonfly
A large, agile aerial predator with an elongated body, enormous compound eyes, and two pairs of strong wings held straight out to the sides at rest, often seen patrolling over water in search of prey.
dragonfly

Banana Spider
"Banana spider" is a folk name applied inconsistently across the Americas, but in the southeastern United States it most often refers to the large, golden-silked orb weaver commonly seen spanning gaps between trees along shaded trails.
spider
Flour Beetle
A tiny, shiny reddish-brown beetle that infests flour, cereal, and other dry stored foods, often found in dense clustered populations.
beetle
Whirligig Beetle
A small, glossy black beetle that spins and darts in rapid circles across the surface film of ponds, often gathered in loose groups, using divided eyes to see both above and below the water at once.
aquatic-insect
Red Velvet Mite
A plump, brilliant red mite covered in a dense coat of short velvety hairs, often seen emerging onto the soil surface in numbers right after a heavy rain. Its vivid color and unusual size for a mite make it one of the more eye-catching arachnids most people will ever encounter.
arachnid
Human Bot Fly
A stout, dark-bodied fly from the American tropics famous for an unusual reproductive trick: it captures a blood-feeding mosquito mid-flight and glues its own eggs to the mosquito's body before releasing it to carry them to a future host. The adult itself is rarely seen, spending most of its short life in shaded forest understory.
fly
Spider Mite
A speck-sized arachnid that spins fine silk webbing across infested leaves as it pierces plant cells for their contents, leaving behind a telltale stippled, bronzed appearance. Populations can explode rapidly in hot, dry weather, making it a familiar garden and greenhouse pest.
arachnid
Rice Weevil
A tiny reddish-brown weevil with a long curved snout and four faint pale spots on its wing covers, commonly found infesting stored rice, wheat, and other grain products.
beetle
Indian Meal Moth
A small, distinctively two-toned moth with pale grey-tan inner wings and coppery-reddish outer wings, widely recognized as the most common moth found infesting stored dry food products in homes.
