Primary reproductives are the king and queen, the
swarmers that started the colony. The king and queen mate periodically,
and the queen may live as long as 25 years.Primary reproductives (king and
queen) range in color from honey to black . They are about 1/4 to about
1/2 inch in length. The male and female mate for life and are responsible
for producing eggs that become the workers, soldiers, and future alates
of the colony.
Supplementary reproductives
are produced in mature colonies or within groups of termites at distant
feeding sites. They have light colored bodies. If the primary queen dies,
the supplementaries can take over. A mature queen can lay thousands of
eggs each year. During the two-week incubation period, eggs are tended
by the worker termites. The nymph hatches directly from the egg. Attendants
feed nymphs regurgitated food for the first two weeks, enabling them through
molting to become workers, soldiers, reproductives, or supplementary reproductives.
As the reproductive nymph matures, its body lengthens and sexual organs
develop. The body turns black, eyes become functional, and wings extend
twice its body length.
These are winged reproductive termites (swarmers). Subterranean termite
alates are day swarmers . After swarming, they drop their wings and look
for a nesting site. Swarms usually occur in the morning after a warm rain.
Winged reproductives
(alates) are coal black to pale yellow-brown, flattened and about 1/4
to 3/8 inch long, with pale or smoke-gray to brown wings. Alates are also
known as "swarmers."
All the mature reproductives
leave the colony at the same time, usually in the spring and sometimes
in the fall. Swarmers are poor fliers and, when above ground, usually
flutter a few yards and fall. Swarmers, emerging outdoors from tree stumps,
railroad ties, etc., are usually not of concern and are in no way an indication
that the structure is infested. After dropping to the ground, they shed
their wings. Surviving males find compatible mates and then burrow into
the ground to become king and queen. These termites live in nests underground
and tunnel up for food, which includes the wood understructure of homes.
A very small percentage
of swarming termites survive to initiate new colonies. Many are eaten
by other insects, birds, etc. Likewise, swarms emerging inside a structure
usually never survive. However, it is an indication of infestation.
Swarmers have straight,
bead-like antennae, a thick waist, and a pair of long, equal-length wings,
that break off easily. The presence of winged termites, or their shedded
wings, inside a home should be a warning of a termite infestation.
They can be differentiated
from adult winged ants that have elbowed antennae, constricted waists,
forewings are larger than the rear wings (unequal size), and not easily
detached.
