A set of nest cells are made sequentially along the length of the stem from back to front. One home security problem that these and other similar bees have is that while the female is out foraging for pollen and nectar another bee or nest parasite of some kind can invade and usurp the nest, steal the pollen, or lay their eggs in the nest. To decrease the possibility of this happening the female, when present in the nest, guards the entrance and when any possible invader arrives she presents her sting end at the opening. To presumably increase the chances that a nest will be successful sometimes two females will occupy the same nest, allowing one to act as guard while the other forages. Experiments have shown that these bees can recognize their nestmates. The chemical signature embedded in their cuticles houses the signal for that recognition. The Red-tipped Twignester is one of only three species in the genus, all restricted to southern South America. They are easy to differentiate by color alone – one is blue, one is smaller and all black, and this one – you can tell what color it is from the picture. ~~~~~~~~~~{{{{{{0}}}}}}~~~~~~~~~~ All photographs are public domain, feel free to download and use as you wish.
