Halictidae is the second-largest family of bees [1] (clade Anthophila) with nearly 4,500 species. [2] They are commonly called sweat bees (especially the smaller species), as they are often attracted to perspiration. [3] [4] Halictid species are an extremely diverse group that can vary greatly in appearance.
Not attracted to lights at night unless nest is disturbed, or light is placed near hive, or bee is sick. [5] Attracted to lights at night [6] [7] Lives in Large colonies of flat, wax-based honeycomb hanging vertically. Small cavities in the soil or sometime above ground in dark cavities. Commonly uses small rodent nests, may use bird cavity nests.
In still other experiments, Menzel explored the timing of bee color learning by testing whether bees register color before, during, or after receiving their sugar-water reward. For this purpose Menzel displayed the color beneath a rewarded dish at different stages of the honey bee feeding process: during approach, feeding and departure. [2]
The special fragrance collection organs are seen on the large hind legs of this Euglossa viridissima as it sleeps on a leaf. Male orchid bees have uniquely modified legs which are used to collect and store different volatile compounds (often esters) throughout their lives, primarily from orchids in the subtribes Stanhopeinae and Catasetinae, where all species are exclusively pollinated by ...
Foraging hornets are also selectively attracted to honey bee colony odors, in particular honey and pollen, as well as honey bee pheromones, which may signal a high prey density. In laboratory assays, workers of V. velutina oriented especially towards geraniol , a component of the honey bee worker aggregation pheromone, that could therefore ...

Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky above 19 °C (66 °F), while at lower temperatures, it becomes hard and brittle. When foraging, worker bees primarily harvest pollen and nectar, while also collecting water and plant resin necessary for the production of propolis. [1]
Like many bees, the females have 11 antennal segments and the males have 10. Augochlorella aurata have a few specific characteristics that define them from other bees with similar appearance. Like many members of Halictidae , the tip of the mandible of these bees is rounded and said to be shaped like a glove or mitten.
