Myrmica is a genus of ants within the subfamily Myrmicinae. [2] It is widespread throughout the temperate regions of the Holarctic and high mountains in Southeast Asia. [2] [3]The genus consists of around 200 known species and additional subspecies, [2] although this figure is likely to rise as soon as the Chinese and Nearctic fauna lists are revised.

Pharaoh ants utilize three types of pheromones. One is a long-lasting attractive chemical that is used to build a trail network. It remains detectable even if the ants do not use the trail for several days. Pharaoh ants cease activity at night and begin each day of work at around 8 am, yet parts of the trail network are identical each day. [11]
Pheromones can be used instead of insecticides in orchards. Pest insects are attracted by sex pheromones, allowing farmers to evaluate pest levels, and if need be to provide sufficient pheromone to disrupt mating. Chemical communication in insects is social signalling between insects of the same or different species, using chemicals.
It is unique in that it reproduces by ejecting pheromones from its postpetiole directly into the mandibles of its mate. Female ants of this species can also reproduce through thelytokous parthenogenesis , but, unlike most ant species during this process, the individual will rupture the membrane of the gaster, causing a burst of secretions ...
Myrmicinae is a subfamily of ants, with about 140 extant genera; [1] their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees. [2]
Depending on the function, there are different emission and reception scenarios. Ants, for example, emit alarm pheromones intermittently or continuously in the usually windless environment of the anthill. Trace pheromones are emitted by an ant as a moving source. Silkmoth sex pheromones are emitted in discrete scent threads in an air stream. [57]
Top: An ant in Mozambique Bottom: An ant-mimicking spider, Myrmarachne Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive.
