life cycle







mating flights

ants mate on wing, flying ants males , elates (virgin queens). mating (or nuptial) flights of lasius niger occur around june september throughout species range; in north america flights occur during autumn, whereas in europe take place during hot summer months of july , august. flights can contain thousands of winged males , females.

disparities between local weather conditions can cause nuptial flights out of phase amongst widespread populations of l. niger. during long-lasting, hot summers, flights can take place simultaneously across country, overcast weather local patches of sunshine results in far less synchronised emergence of alates (winged individuals).

once queens have mated land , discard wings , begin find suitable place dig tunnel. meanwhile, males live day or 2 after mating flights , die.

new nest

after removing wings, queen move find moist ground, start digging tunnel. once tunnel has been completed, queen block entrance , retreat bottom. subsequently, dig out small chamber. serve claustral chamber of new colony. generally, queen begin lay eggs after construction of chamber, , eggs hatch after 8–10 weeks. until eggs hatch , larvae grow maturity, lasius niger queen not eat, relying on protein of wing muscles broken down , digested. in cases, lasius niger queen may eat own eggs in order survive.

egg ant

lasius niger nest

lasius niger have 4 stages of development: egg, larva, pupa, , adult. lasius niger lay tiny, white, kidney-shaped eggs smooth sticky surface helps them carried in group instead of 1 one. after hatching lasius niger proceed onto larva stage resembling tiny maggots. larvae need fed queen (or workers in case of established colony) if mature; feed larvae grow, shedding skin, doing 3 times in total. each molt, larvae grow hooked hairs allow them carried in groups. when lasius niger larvae reach last molt big carried part of group , carried singly. once larva grows big enough spins cocoon around itself. aid process queen (or workers) may bury larva can spin cocoon undisturbed, , begin process of metamorphosis. once process complete lasius niger worker emerges cocoon. @ stage lasius niger white darken on course of hour until has turned black.

colony established

the first worker ants emerge small compared later generations. @ point workers begin expand nest , care queen , brood; remove seal entrance nest , begin forage above ground. critical time colony need gather food support future growth , particularly feed starved queen, have lost around 50% of body weight. point on queen s egg laying output increase significantly, becoming queen s sole function. later generations of worker ants bigger, stronger , more aggressive because there more nutrition them @ larval stage. initial brood being fed scarce resources available queen smaller brood supported team of foraging , nursing workers. provided workers able find food, @ stage colony see exponential rise in population. after several years, once colony established, queen lay eggs become queens , males. black ants make large nests extensive tunnel connections.
