Solenopsis daguerrei is a species

Species

In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Ant

Ants are social insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. More than...

A pheromone is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual...

s which are very similar to those produced by the queens of the host species. The young queen finds a queen of the host species and latches onto it, eating the food intended for the host queen and slowly killing it. The S. daguerrei queen then begins laying eggs. These are taken care of by the host ants, sometimes preferentially to their own brood. S. daguerrei only produce winged virgin queens and males. No workers are needed, since these are provided by the host species. The winged ants fly off

Nuptial flight

Nuptial flight is an important phase in the reproduction of most ant, termite and some bee species. During the flight, virgin queens mate with males and then land to start a new colony, or, in the case of honey bees, continue the planned succession of an existing hived colony.- Before the flight :A...
