Black hornet colonies contain between 100 and 400 members at their peak.
Queens dominate community hornet hives. They are the only female in the hive to reproduce.
Queens take around six days to hatch eggs. It takes around nine to 10 days for hornets to grow into adults.
Female black hornets do all the work. They are produced all summer and do everything from gathering food to acting as the hive's guardians.
Black hornet wasp nests (which are as big as a basketball) are made from a papery pulp that consists of chewed-up wood fibers and saliva.
Just like other stinging insects, black hornets can be aggressive, and they will not hesitate to attack anyone or anything that invades their space. However, there are plenty of ways to reduce your risk of getting stung by a hornet, such as never wearing bright colors or perfume when you're outdoors. Most importantly, you should never try to swat a black hornet because this will only signal to the rest of the colony that it's time to strike.
The mature colony consists of a queen and usually anywhere from 100 to 400 workers by summer's end. Then, in the fall, males and new queens are produced. In the winter in colder climates, black hornet nests are abandoned, and only new, young queens (along with their eggs) survive the season.
DONT ! The black hornet is a protective insect, and unfortunately, it can become aggressive when threatened and will sting repeatedly if its nest is disturbed or if its space is invaded in any way. The venom from black hornets is different from that of bees, and it may elicit a more painful sting. Also, hornets have smooth stingers, so they can sting over and over again. This is another difference from bees, who are only able to attack once before their stinger falls off.
The black hornet insect is roughly 5/8-inch to 3/4-inch long and is distinguished by the striking, black-and-white patterns on the face, abdomen, thorax and first antennal segment. It's mostly hairless, and the face is primarily white with dark eyes. The insect's large antennae are conspicuous.
Males do differ from females somewhat in that they have an additional white band on the first abdominal segment as well as on the tip. Also, female hornets have 12 antennal segments, whereas males have 13. The queen is the largest insect in the colony, although queens and workers are almost the same size.
The front wings of black hornets and other members of the Vespidae family are folded lengthwise when at rest, which is another primary identification factor. Black hornets are also known for their huge, ball-shaped, distinctive-looking nests, which they build in the springtime. These nests can be as large as 14 inches in diameter and more than 24 inches in length. They're typically 3 or 4 feet off the ground and can be found on trees, shrubs, houses, utility poles, sheds and other structures.
