⭐ Core Definition: Crematogaster

Crematogaster is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal (tree-dwelling). These ants are also known as acrobat ants.

Cocktail ants acquire food largely through predation on other insects, such as wasps. They use venom to stun their prey and a complex trail-laying process to lead comrades to food sources. Like most ants, Crematogaster species reproduce by partaking in nuptial flights, where the queen acquires the sperm used to fertilize every egg throughout her life.

👉 Crematogaster in the context of Trail pheromone

Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species. Specifically, trail pheromones are often incorporated with secretions of more than one exocrine gland to produce a higher degree of specificity. Considered one of the primary chemical signaling methods in which many social insects depend on, trail pheromone deposition can be considered one of the main facets to explain the success of social insect communication today. Many species of ants, including those in the genus Crematogaster use trail pheromones.

Crematogaster in the context of Queen ant

A queen ant (also known as a gyne) is an adult, reproducing female ant in an ant colony; she is usually the mother of all the other ants in that colony. Some female ants, such as the Cataglyphis, do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning, and all of those offspring will be female. Others, like those in the genus Crematogaster, mate in a nuptial flight. Queen offspring ants among most species develop from larvae specially fed in order to become sexually mature.

Depending on the species, there can be either a single mother queen, or potentially hundreds of fertile queens. Not every colony of ants has a queen. Some colonies have multiple queens.

Crematogaster in the context of Vachellia seyal

Vachellia seyal, the red acacia, known also as the shittah tree (the source of shittim wood), is a thorny, 6– to 10-m-high (20 to 30 ft) tree with a pale greenish or reddish bark. At the base of the 3–10 cm (1.2–3.9 in) feathery leaves, two straight, light grey thorns grow to 7–20 cm (2.8–7.9 in) long. The blossoms are displayed in round, bright yellow clusters about 1.5 cm (0.59 in) diameter.

In Vachellia seyal var. fistula, which is more common on heavy clay soils, some of the thorns are swollen as domatia, housing mutualistic ants such as Crematogaster.
