hello all,
i noticed a great deal of ant-flies (ants with wings) in my garden on
saturday and now those nests seem deserted. i guess they fly off to start
new colonies elsewhere.
does this mean no more ants till next year? what is the life cycle of the
ant or ant-colony?
many thanks,
Harry.
Not quite sure it's a diy thing, but still...
Flying ants are the new queens and males - raised that year in the old
nest. Queens bigger, males smaller. The new (virgin) queens take
flight, followed by the males. Mating mid-air ensues - and then
wherever the queens land, they rub their wings off, and look for a
suitable site for a new nest. Males unfortunately land and die - they
have no further use in the ant lifecycle. The original nest continues -
but underground - you only see the fine earth piled up in the run up and
shortly after the flights, while the newly mated queens go off to set up
their own nest. Eventually she will have a functioning nest, complete
with worker ants, and will produce the next generation of queens and
males ready to take to the wing and start the cycle all over again.
Nests survive from year to year, unless neighbouring ant colonies invade
and wipe it out, so if you have ant hills in your lawn/borders once,
chances are you'll get them this sort of time again next year, and the
year after...
On the other hand, ants apparently do a good job at pest control -
though I must say their farming of aphids leaves a lot to be desired IMO.
