Tachypompilus ferrugineus

只是會痛會痛，但不會對你造成嚴重傷害。

螫吃：肉

The rusty spider wasp is a reddish-brown wasp that hunts large spiders, mainly wolf spiders. It lives across a huge area of the Americas, from southern Canada to South America and the Caribbean. Females catch a spider, paralyse it and use it to feed their young.1

牠吃什麼？

Adults feed on nectar and aphid honeydew from flowers. Females hunt large spiders, mainly wolf spiders, dragging them along the ground by the chelicerae or pedipalps, walking backwards. The larva then feeds on the live paralysed spider.1

怎麼認出牠

Mostly reddish-brown body1
Four narrow dark bands circling the abdomen1
Violet-blue wings1
Body length of 15 to 25 mm1

常被誤認為： The red-tailed spider wasp name is also used for the Asian species Tachypompilus analis, so the name alone does not tell you which species you have.1

毒液從螫針出來。

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

如果牠螫人

把蜜蜂的螫針刮掉，然後冷敷患處。
如果傷者呼吸困難、臉部或喉嚨腫脹，或覺得快要昏倒，這就是過敏急症：打緊急電話，如果傷者有腎上腺素自動注射筆，就使用它。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠螫了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

牠有多快？

一隻家蠅 大約 7 km/h (4,4 mph)

值得知道

小知識

Mating pairs scissor their wings face to face, which is unusual for spider wasps, which normally flick their wings vertically.1

Males and females both shelter in a crevice at the base of a monument at night and when it rains, and up to eight wasps have been seen there at once.1

The female camouflages the nest with pieces of debris from nearby.1

Females have been seen dragging leaves into their nests in Ohio.1

In southern Canada, the dark fishing spider Dolomedes tenebrosus has been recorded as prey.1
