One of the largest spiders in North America, the fishing spider can walk on water, dive beneath the surface to escape danger, and ambush small fish and tadpoles with its front legs from the water's edge.

Bark Scorpion
A slender, pale tan scorpion best known for its unusual habit of climbing trees, walls, and rock faces rather than staying on the ground like most scorpions. Its thin build and long, narrow tail set it apart from the stockier, heavy-clawed scorpions found elsewhere.
arachnid
Fireflies (Lightning Bug)
A soft-bodied beetle that turns summer evenings magical by flashing rhythmic patterns of cold light from its abdomen to attract mates across meadows and forest edges.

Leaf Miner
Rather than chewing from the outside, a leaf miner larva tunnels between the upper and lower surfaces of a leaf, leaving behind pale, winding trails or blotches that trace its path as it feeds.
fly
Bald-faced Hornet
A black-and-white social wasp, actually a type of yellowjacket rather than a true hornet, best known for building large, football-shaped gray paper nests suspended from tree branches or eaves.

Cicada
A stout, big-eyed insect best known for the loud, buzzing chorus of song produced by males, and for periodical species that emerge from the ground by the millions after living underground for over a decade.

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
Bagworm Moth
A moth best known for its larva's habit of constructing and living inside a spindle-shaped case of silk and plant debris that hangs from twigs, with adult males a plain sooty-winged moth and females remaining wingless and grub-like inside the bag for life.
