Haplodiploidy is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. [1] Haplodiploidy is sometimes called arrhenotoky. Haplodiploidy determines the sex in all members of the insect orders Hymenoptera (bees, ants, and wasps) [2] and Thysanoptera ...
Diploid males are known to be produced by inbreeding in many ant, bee, and wasp species. Diploid biparental males are usually sterile but a few species that have fertile diploid males are known. [13] One consequence of haplodiploidy is that females on average have more genes in common with their sisters than they do with their daughters.
However, despite the shortcomings of the haplodiploidy hypothesis, it is still considered to have some importance. For example, many bees have female-biased sex ratios and/or invest less in or kill males. Analysis has shown that in Hymenoptera, the ancestral female was monogamous in each of the eight independent cases where eusociality evolved. [2]
In another species of sweat bees, L. calceatum, social phenotype has been predicted by altitude and micro-habitat composition, with social nests found in warmer, sunnier sites, and solitary nests found in adjacent, cooler, shaded locations. Facultatively social bee species, however, which comprise the majority of social bee diversity, have ...
Bombus muscorum, commonly known as the large carder bee or moss carder bee, is a species of bumblebee in the family Apidae. The species is found throughout Eurasia in fragmented populations, but is most commonly found in the British Isles .
Bees were seen creating beautiful patterns while "wiggle dancing" on their nest in Kon Tim, Vietnam.
B. terrestris bees exhibit alloethism, which is where different sized bees perform different tasks. This kind of behavior can be seen most often in foraging activities. Larger bees are more often found foraging outside the nest and will return to the nest with larger amounts of nectar and pollen.
