Diacamma rugosum, also known as the Bornean queenless ant or Asian bullet ant, is a species of ant of the subfamily Ponerinae. It is found in many countries throughout Southeast Asia. 20 subspecies are recognized. [1] Diacamma rugosum is noted for being one of the only species of ants to completely lack a queen caste.
In Diacamma only one worker retains her gemmae in each colony, she is the gamergate (mated egglaying worker), and she bites off the gemmae of newly emerged workers. Mutilation causes the degeneration of the neuronal connections between the sensory hairs on the gemma's surface and the central nervous system , and this may explain the ...
Egg position in the cell is a good indicator of a laying worker. A queen bee's abdomen is noticeably longer than a worker, allowing a queen to lay an egg at the bottom of the cell. A queen bee will usually lay an egg centered in the cell. Workers cannot reach the bottom of normal depth cells, and will lay eggs on the sides of the cell or off ...
Queen (marked) surrounded by Africanized workers . A queen bee is typically an adult, mated female that lives in a colony or hive of honey bees.With fully developed reproductive organs, the queen is usually the mother of most, if not all, of the bees in the beehive. [1]
When a colony accidentally loses its queen, it is said to be queenless. [95] The workers realize the queen is absent after around an hour as her pheromones in the hive fade. Instinctively, the workers select cells containing eggs aged less than three days and dramatically enlarge the cells to form "emergency queen cells".
Butler may have misinterpreted the queen's function when he found queenless colonies sometimes develop eggs laid by "laying workers", however there is no doubt he saw the queen as an Amazonian ruler of the hive. As an influential beekeeper and author, his assertion that drones are male and workers female, was quickly accepted.
Cloake board insertion: The Cloake board is placed between two hive bodies when the queen is known to be in the lower hive body. Because a Cloake board either contains or is used with a queen excluder, the laying queen will be restricted to the lower hive body from this point forward.
Worker policing is found in honey bees and other hymenopterans including some species of bumblebees, ants and wasps.. Worker policing is a behavior seen in colonies of social hymenopterans (ants, bees, and wasps) whereby worker females eat or remove eggs that have been laid by other workers rather than those laid by a queen.
