毒力

皮肤里有毒

它的皮肤有毒。摸、舔或吃都很危险。

它的毒会造成什么？

This beetle is poisonous rather than venomous, as it does not bite or sting. It contains cantharidin, a toxic compound that causes blistering of the skin and mucous membranes. In horses, a dose of about one milligram per kilogram of body weight is toxic, and eating 30 to 50 beetles can be fatal. Symptoms include blisters and ulcers of the mouth, pawing, stretching, diarrhoea, and low blood calcium and magnesium.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

Cantharidin has been known to cause deaths, particularly of horses. Even two to five beetles can cause colic in horses, and hay containing crushed beetles can make animals ill. Cattle and sheep are less affected but can still show some symptoms. Frogs that eat these beetles keep the poison, so eating frog legs from beetle-fed frogs could cause poisoning, as little as 200 grams could contain a potentially fatal dose.1

值得了解

事实

Frogs can eat blister beetles without harm, but they store the poison in their tissues and mucus, so predators that eat the frogs can be poisoned.1

Its larvae live on grasshopper eggs, which they find and feed on.1

Some ecologists consider it one of the most problematic pest blister beetles in its range, because it feeds voraciously, damages fruit and forms swarms.1

The beetle changes its appearance as it develops. The newly hatched larva is whitish with long legs, and later becomes a reddish-brown grub with shorter legs.1

Predators include robber flies and birds such as the western meadowlark, eastern bluebird and scissor-tailed flycatcher.1
