Palo Verde Beetle:
Size: 3-4 inches with long antennae
Alias: HUGE ROACH! (It's a beetle, not a roach)
Habitat: Palo verde tree roots as well as other tree varieties that are stressed from lack of water.
Life Cycle: Females lay eggs in soil underneath Palo Verde trees. Once hatched, the larvae will burrow into tree roots (larvae reach lengths of 4 inches). Larvae then go through 3 stages, increasing in size each time. Adults emerge from an exit hole and begin a 3 year life cycle and die shortly after mating and egg laying.
Danger: Kills roots of trees, eventually killing the tree. No known danger to humans
Cicada:
Size: 1-2 inches
Diet: crops, tree sap and tree roots
Alias: Locust
Habitat: Cicadas live underground.In the final nymphal instar, they construct an exit tunnel to the surface and emerge. They then molt (shed their skins), on a nearby plant for the last time and emerge as adults. The abandoned skins remain, still clinging to the bark of trees.
The buzz: Cicada's are famous for the annoying buzzing they produce during summer evenings. This is produced only by males from a noisemaker called a "tymbal"
Crane Fly:

Bed Bug:
Size: 1/6-1/4 inch
Diet: Blood of humans. However, in desperation they may get a blood meal from birds or rodents.
Habitat: Human dwellings
Life cycle: Females lay 15-20 eggs at a time until they produce 200-500 eggs. Eggs hatch in 6-10 days in warm weather or heated structures. Well fed adults live up to a year and a half and at least 3-4 generations are produced a year.
Bites: Most people do not feel the actual bite itself but a painful itching and large inflamed spot make their presence known. However, a bed bug infestation should not be determined just from bite marks alone.
Brown dog tick:
Size: 1/8 and up to 1/2 inch when engorged with a blood meal.
Diet: Dog blood
Habitat: Yards, kennels and homes.
Life cycle: Females will feed on their host for about a week, drop off and find a place to lay their eggs. The female can lay up to 5000 eggs over a period of two weeks and development is heavily dependent on temperature. The female will die after laying her eggs. Developing ticks require a blood meal at each stage of life: larva, nymph and adult.
Bites: The brown dog tick has not been found to transmit diseases to humans. However, the Deer tick can vector Lyme Disease.
