Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter.
In some species, the larvae are predatory themselves; the wasp eggs are deposited in clusters of eggs laid by other insects, and these are then consumed by the developing wasp larvae. [10] The largest social wasp is the Asian giant hornet, at up to 5 centimetres (2.0 in) in length. [11]
Commonly known as cuckoo wasps or emerald wasps, the hymenopteran family Chrysididae is a very large cosmopolitan group (over 3000 described species) of parasitoid or kleptoparasitic wasps, often highly sculptured, [1] with brilliant metallic colors created by structural coloration. [2]
Vespula pensylvanica, the western yellowjacket, is a Nearctic species of wasp in the genus Vespula. [1] [2] It is native to regions of North America, largely in areas with northern temperate climates. Its reproductive behavior is constrained by cold weather, which successfully reduces the number of western yellowjackets in cold months.

Wasp season is typically between March and November but the bugs are especially active now after a mild winter and spring. “This is a really big year for wasps,” said Lynn Kimsey, director of ...
The fauna of the state of Oregon includes a wide array of species. The common nighthawk is one of more than 50 species of birds seen in the John Day Fossil Beds National Monument. The western meadowlark is Oregon's state bird. The North American beaver is Oregon's state mammal. One way of presenting the fauna of Oregon is classification by ...
Diploid males are known to be produced by inbreeding in many ant, bee, and wasp species. Diploid biparental males are usually sterile but a few species that have fertile diploid males are known. [13] One consequence of haplodiploidy is that females on average have more genes in common with their sisters than they do with their daughters.
