English: A Carpenter bee robber fly on the Springbok Flats, Limpopo, South Africa. It was observed near a female Xylocopa caffra. The Robber fly larvae parasitize the Xylocopa larvae. They bore out of the nests and leave their old larval integument hanging from the wood. The adults may also prey on the adult carpenter bees.
Solitary bees tend to be gregarious and often several nests of solitary bees are near each other. In solitary nesting, the founding bee forages, builds cells, lays the eggs, and guards. Normally, only one generation of bees live in the nest. [9] Xylocopa pubescens is one carpenter bee species that can have both social and solitary nests. [9]
As X. pubescens is a large carpenter bee, it prefers medium to large size flowers. Zygomorphic flowers with bilateral symmetry are also preferable. Plants only produce nectar and/or pollen at certain times of the day, while balancing sugar and water amounts in the nectar for foraging bees.
Female X. virginica. The bee is similar in size to bumblebees, but has a glossy, mostly black body with a slight metallic purple tint. [4] X. virginica males and females have generally the same mass, but can be differentiated visually by the male's longer body and the female's wider head.
The Queen Alexandra's birdwing is the largest species of butterfly. The largest lepidopteran species overall is often claimed to be either the Queen Alexandra's birdwing (Ornithoptera alexandrae), a butterfly from Papua New Guinea, or the Atlas moth (Attacus atlas), a moth from Southeast Asia. Both of these species can reach a body length of 8 ...
Ceratina calcarata is a subsocial bee, meaning that there is extended care of the offspring and prolonged interaction between parent and offspring; [11] however, there are no other interactions between individuals of this species except for mating. Females clean and defend their progeny into adulthood.
With more than 271,000 colonies, Texas now has the third-most colonies in the country, sitting behind California, with more than 1.3 million colonies, and Florida, which has about 318,900 colonies.
There are reports of the honey bee, Apis mellifera, having negative effects on X. californica populations. The carpenter bees are attracted to the floral scents of the honey produced by the honey bees; X. californica may come near or inside their hives and get attacked by the hive resulting in the death of the carpenter bee.
