Cydnidae are a family of pentatomoid bugs, known by common names including burrowing bugs or burrower bugs. [2] As the common name would suggest, many members of the group live a subterranean lifestyle, burrowing into soil using their head and forelegs, only emerging to mate and then laying their eggs in soil.
Clubtails are fast-flying dragonflies with short flight seasons. They spend much time at rest, perching in a suitable position to dart forth to prey on flying insects. They tend to perch on the ground or on leaves with the abdomen sloping up and its tip curling down a little. Larger species may perch with a drooping abdomen or lie flat on a leaf.
Fairyflies are very tiny insects, like most chalcidoid wasps, mostly ranging from 0.5 to 1.0 mm (0.020 to 0.039 in) long. They include the world's smallest known insect, with a body length of only 0.139 mm (0.0055 in), and the smallest known flying insect, only 0.15 mm (0.0059 in) long. They usually have nonmetallic black, brown, or yellow bodies.
The mandibles give these attractive insects a ferocious appearance. While tiger beetles are voracious predators of small arthropods, they do not bite humans unless handled. Both the common name and the species name refer to the six small white spots on the beetle's metallic-green to metallic-blue-green elytra.
They line their burrows with silk threads and mud. They use their disk to plug the opening of the burrow. [6] When a small insect would step on its disk (sometimes referred to as a "copper coin"), Cyclocosmia ricketti will then purportedly shrink its abdomen to allow its prey to fall further into its burrow to be devoured.

The pronghorn clubtail is a medium-sized dragonfly with a length of 1 7/8 to 2 1/8 inches (47 to 54 mm). Its face and its thorax are olive green, with the thorax marked with dark brown stripes. Its abdomen is dark brown to black and is marked along the top with a line of elongated, triangular-shaped marks varying in color from greenish to yellow.
On this high quality closeup, head anatomic details are well visible. The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles.
Blue bottle flies are typically 10–14 mm (3 ⁄ 8 – 9 ⁄ 16 in) long, almost twice the size of a housefly. The head and thorax are dull gray, and the back of the head has long yellow-orange setae. [5] [6] The abdomen is bright metallic blue with black markings. Its body and legs are covered with black bristly hairs.
