These photos were taken my my neighbour Derry who is also interested insects. The hornet nest was taken locally by the river a year ago. Its an insect that I search and search for and while I did find a nest by the river it was to high up to photograph.
Hornets appear very similar to common wasps, but are larger and coloured chestnut-brown (rather than black) and yellow. The largest of the British social wasps, they build papery nests in hollow trees, although hornet nests have been discovered in wall cavities and chimneys.
The hornet’s life cycle is similar to that of the common wasp. Newly-mated queens hibernate during the winter, and emerge in spring to begin building a nest. They lay eggs that hatch into sterile female workers who take over nest building and collecting food for the developing larvae. Later in the summer males and fertile females hatch. These mate and the females become next year’s queens. The males, old queen and workers die in the autumn.
