Asian giant hornet (Vespa mendarinia)–This is one really big wasp
It’s summer. which in this neck of the woods means wasp and hornet season (they are different, btw). Well I’m glad these buggers aren’t around here:
A few interesting notes on Vespa mandarinia’s venom and stinger:
* The venom contains at least eight distinct chemicals, some of which damage tissue, some of which cause pain, and at least one which has an odor that attracts more hornets to the victim.
* The venom contains 5% acetylcholine, a greater concentration than is present in bee or other wasp venoms. Acetylcholine stimulates the pain nerve fibres, intensifying the pain of the sting.
* Vespa mandarinia uses its large crushing mandibles, rather than its sting, to kill prey.
* The venom of the Asian giant hornet is more toxic than that of most other bees or wasps, giving this species one of the greatest lethal capacities per colony.
* Like all hornets, V. mandarinia possesses a barbless stinger, allowing it to sting repeatedly. Source: IgwanaRob
Oh that’s not enough? Check out the picture:
As the author of the post said, see these coming your way, running and screaming like a little girl is not only acceptable but probably encouraged.

Now that one gives me the creeps and hopefully won’t discover out house. They seem to love the heat and love to build nests above our front door! It’s a constant battle with them! But, none of them are that big!! Thank goodness
Wow, that’s even larger than a bumble-bee (which, according to one theory, can’t even fly).
I find it interesting that bees use what amounts to nerve agents (or, perhaps, more specifically, anti-nerve agents):

Also, note that Acetylcholine doesn’t just involve the pain response, but also is involved in muscular control, as well as in the brain.
