Wolf Spider
A robust, hairy, ground-dwelling spider with excellent night vision and a habit of chasing down prey rather than trapping it in a web; females are often seen carrying an egg sac or a back full of spiderlings.

beetle
Bumblebee Carpenter Bee
A large, robust bee that closely resembles a bumblebee at a glance but has a smooth, shiny, hairless abdomen and a habit of boring round nesting tunnels into bare wood.
bee
Toad Bug
A squat, warty-looking true bug with bulging eyes and a mottled brown pattern, so named for its uncanny resemblance to a tiny toad as it hops along muddy shorelines.
aquatic-insect
Yellow Jacket
A smooth-bodied, boldly banded black-and-yellow wasp with a narrow waist, often seen hovering aggressively around outdoor food and sugary drinks in late summer.
wasp
Rose Hair Tarantula

A black-and-yellow social wasp closely resembling the common wasp, distinguished by three black facial dots, that builds large paper nests in wall voids and roof cavities and is widespread in both its native and introduced ranges.
wasp
Pine Processionary Moth
An unremarkable grey-brown moth known almost entirely through its larvae, which build large silken nests in pine trees and travel to feed in long, head-to-tail processions covered in fine defensive hairs.
moth
Fork-tailed Bush Katydid
Slimmer and greener than its treetop relatives, the fork-tailed bush katydid lives among shrubs and garden plants, with males identified by the distinctive forked appendages at the tip of the abdomen that give the species its name.

Slender, long-waisted wasps that build distinctive nests from mud, mud daubers stock their cells with paralyzed spiders. Their tube or urn-shaped mud nests are common under eaves and bridges.
wasp

This small, oval water beetle earns its name from the loud squeak it produces when picked up, a sound made by rubbing internal body parts together rather than by any vocal organ.
beetle
Common Baskettail
One of the earliest dragonflies to appear each spring, this brown, green-eyed skimmer often swarms in numbers over sunny clearings before most other species have emerged.
dragonfly
Confused Flour Beetle
A tiny, flattened, reddish-brown beetle commonly found in stored flour and grain products, distinguished from its near-identical relative the red flour beetle mainly by its antennae shape.
beetle
