The venom of Vespa luctuosa has the highest recorded toxicity to mice of any wasp species tested. The LD 50 of the venom is 1.6 mg/kg. The toxicity (measured against mice) per weight of Vespa luctuosa venom is higher than that of the larger Asian giant hornet (Vespa mandarinia), which has an LD 50 of 4.0 mg/kg, but which is responsible for many more human deaths than Vespa luctuosa due to the ...
