Generally, the killer hornet can grow to a length of approximately 2 inches. The queen hornet is slightly bigger in size, growing up to a length of 2.2 inches. It sports a wingspan of 3 inches, which comes handy in flight. It has the ability of flying at the speed of 25 - 30 mph and can easily cover a distance of 60 miles in a day.
A single killer hornet can kill approximately 40 honey bees per minute.They attack bee hives in large swarms and feed on honey bees and their larvae. Even a small swarm of hornets can easily destroy a 30,000 member bee colony in no time. After the entire bee swarm is annihilated, they carry the bee larvae to their own nests to feed their larvae.
The venom contains a cytolytic peptide which stimulates the phospholipase action and damages tissues to cause death.
The venom contains a cytolytic peptide which stimulates the phospholipase action and damages tissues to cause death.The presence of mandaratoxin, a neurotoxin, the venom can turn out to be lethal for humans, if injected in significant amount.
The enzymes present in its venom are so strong that they can dissolve human tissues. Death though, is attributed to anaphylactic shock, an allergic reaction known to make the person lose consciousness and lead to breathing failure.
Even though the powerful insect is seldom threatened by any predator, it does suffer from human intrusion in its natural habitat.Loss of habitat due to human intervention is responsible for the drastic depletion in killer hornet population. In Japan, it is considered a delicacy, owing to which the Japanese indulge in their hunting despite the risk involved.
