Meet the “meat bees.”
Yellowjackets, generally often called “meat bees,” compared to the “vegetarian” honey bees, shall be among the many wasps featured on the Bohart Museum of Entomology‘s open home from 1 to 4 p.m., Sunday, Sept. 25 in Room 1124 of the Tutorial Surge Constructing, 455 Crocker Lane, UC Davis campus. The theme: “Bizarre and Fantastic Wasps.”
The open home is free and household pleasant. A household arts and crafts exercise can be deliberate.
“Yellowjackets are social wasps that construct giant, hidden nests,” writes Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology, on one of her on-line truth sheets. “The nests are often subterranean in rodent burrows or in cavities in timber, partitions or attics.
“Yellow jacket nests may be big with 50,000 to 100,000 staff,” Kimsey factors out. “In temperate climates these colonies are annual. Their nests die within the fall after producing new queens. New queens produced by the colonies within the fall spend the winter in protected locations till spring after they discovered new colonies. Yellow jacket colonies can grow to be perennial in hotter climates, equivalent to in Hawaii and coastal California. In these conditions the nests can grow to be monumental, with thousands and thousands of staff!”
Kimsey says that yellowjacket nests “may be distinguished from paper wasp nests as a result of the brood cells are encased in a paper envelope to allow them to’t be seen with out taking off the outer envelope. These wasps usually feed on stay prey, however the pest species, equivalent to Vespula pensylvanica, will scavenge different sources of meat and sugar, together with sodas, hamburgers and highway kill. They will even go to aphids and scale bugs for honeydew.”
On the open home, guests will be taught concerning the smallest fairy wasps to the “homicide hornets”; what function wasps play in plant galls and figs; and distinguish a parasitoid from a parasite. Kimsey will focus on the Asian large hornet, Vespa mandarinia. A single colony of the Asian large hornet was discovered and destroyed Sept. 18, 2019 in Nanaimo, Vancouver Island, Canada, and a single useless hornet was discovered Dec. 8, 2019 in close by Blaine, Wash. Since then, it additionally has been sighted– and destroyed–in each Canada and Washington state.
Fairy wasps, within the household of chalcidoid wasps, are tiny bugs. They embody the world’s smallest recognized insect, with a physique size of solely 0.139 mm (0.0055 in), and the smallest recognized flying insect, solely 0.15 mm (0.0059 in) lengthy, in accordance with Wikipedia. The fairy wasps are present in temperate and tropical areas all through the world. The household accommodates roughly 100 genera with 1400 species. All recognized fairy wasps are parasitoids of the eggs of different bugs, Wikipedia says, “and several other species have been efficiently used as organic pest management brokers.”
