Dolichovespula sylvestris, the Tree wasp

Queens emerge from hibernation in May. Workers forage from the end of May to September.
Found in woodlands, and hilly regions, and tend to like warm places. Nest at ground level or in cavities in the ground, bird boxes, under eaves, roof spaces, hollow trees and bushes. Apart from man-made structures this wasp will scrape wood for her nest from de-barked trees. The nest is yelowl-grey, and can have hundreds of cells. At maturity at the end of summer there can be 250 workers and the same number of males in a nest.

Liostenogaster flavolineata

Liostenogaster flavolineata

Liostenogaster flavolineata, also known as the Tropical hover wasp is found in South Asian rainforests. Its colonies are small, as can be seen in the nest above, but there can be many colonies close together. The nest is built using mud, so they tend to be located near water. Under rocks and bridges are the most common locations.

As the climate is not seasonal, this wasp does not have a yearly life cycle, and after the founding queen dies the nest is often reused by another queen.
