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.
One of the colors was the same as that used during the initial trial, and the others were novel, unrewarded colors. Remarkably, after a single trial and several days without exposure to the rewarded color, bees correctly chose to explore the color used in the first trial more than fifty-percent of the time.

It is shown that red and white flowers pollinated by bees are of higher spectral purity as compared to bird-pollinated ones and are therefore easier to detect for bees. [8] Bees have trichromatic vision with maxima of peak sensitivities in UV (344 nm), blue (436 nm) and green (544 nm). [ 10 ]
Baltimore Checkerspot (Euphydryas phaeton) nectaring at daisy (Argyranthemum)Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
A familiar example is the resemblance of harmless hoverflies (which have no sting) to bees. Müllerian mimicry, where two or more distasteful or dangerous animal species resemble each other. This is most common among insects such as wasps and bees (hymenoptera). Batesian mimicry was first described by the pioneering naturalist Henry W. Bates ...
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.

Orchids, like many plants, attract specific groups of male euglossine bees by producing species-specific scent mixtures, which likely act as reproductive isolation mechanisms. Some orchids exhibit morphological adaptations that ensure pollinia are only released upon visitation by particular bee species, depending on their size and behavior.
