Large paper nest, upside down pear shaped, hanging from branches and eaves; also barns and attics. Some yellowjacket species nest in the ground. Very large paper nest in hollow trees, sheltered positions. Has a brown, protective layer when the nest is in an unsheltered position. Also found in barns, attics, hollow walls and abandoned bee hives.
These nests are small compared to honeybee hives, which hold about 50,000 bees. Many species nest underground, choosing old rodent burrows or sheltered places, and avoiding places that receive direct sunlight that could result in overheating. Other species make nests above ground, whether in thick grass or in holes in trees.
They tend to be solitary, but sometimes nest close together in aggregations. Species in the genus build cells in underground nests that are lined with a cellophane-like plastic secretion, a true polyester, [2] earning them the nickname polyester bees. [3] As of 2012 there were about 469 described species, and an estimated total around 700. [4]
There are over 20,000 known species of bees in seven recognized biological families. [2] [3] [4] Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.
Creeping thyme (thymus serpyllum) is a wonderful ground cover that is salt-tolerant but does need full sun and well-drained soil to thrive. As always, matching the plant to all the growing ...
The Andrenidae (commonly known as mining bees) are a large, nearly cosmopolitan family of solitary, ground-nesting bees. Most of the family's diversity is located in temperate or arid areas (warm temperate xeric). It includes some enormous genera (e.g., Andrena with over 1300 species, and Perdita with over 700).
All species of Agapostemon nest in the ground, sometimes in dense aggregations. Some species are communal, such as A. virescens.In this and other communal species, multiple females share the same nest entrance, but beneath the common entrance burrow, they construct their own portion of the nest.
