The Independent is announcing imminent mating flights of Britain’s most common formicid, the garden ant Lasius niger:
One of the British summer’s greatest spectacles is upon us – flying ant day. Enormous numbers of flying ants are expected to take advantage of the hot weather today or tomorrow to perform their yearly mating ritual, or “nuptial flight”.
In some places, the flying has already begun. In the aftermath, they will cover pavements and gardens, land on cars and passers-by, and attract swarms of seagulls eager for a free feast.
If you’re over there and inclined to help myrmecologists study the flights, you can log your observations at the Society of Biology’s Flying Ant Survey.
Also, the flights will be an easy opportunity to get yourself started with a pet ant colony. Rearing a colony from a mated queen is often easier than excavating a mature nest.
