How Big Are Cicada Killer Wasps?
WouterAmong the large insect species in North America, the Cicada Killer Wasp is a large insect. These large wasps are black with yellow or orange markings on the thorax and abdomen. They are nearly two inches long. They can be found in sandy areas in parts of Central and South America, and are a common pest in Iowa. They are not dangerous, but their nesting aggregations can damage turf. They are also a nuisance because their nests can form unsightly mounds of soil.
The female Cicada Killer Wasps are large insects with a tubular egg laying structure. They lay eggs in the cavities of cicadas, and the cicadas help feed the larvae. They may dig several chambers in a single year. The eggs hatch in two or three days, and the larvae spin a cocoon of silk mixed with soil. They then overwinter in the cells.
They are large solitary wasps. They do not usually interact with humans, but will sting if they are provoked. The cicada killer wasp is not dangerous, and poses no threat to humans.
Females are usually twice as large as males. They may not defend their burrows, but will bring cicadas to feed the larvae. These females may gather up to 100 cicadas in their lifetime. Their nesting burrows are usually dug in sandy areas near sidewalks and flower beds. They are not particularly aggressive, but they do fly erratic.
Males are smaller than females and are mainly interested in mating. They fly erratic, but will occasionally poke a false stinger at enemies. They may also investigate anything that moves.
