Cinnabar moth

Tyria jacobaeae

名字的由來： The moth is named after cinnabar, a red mineral, because of the red patches on its black wings.1

無害對人無害。不用擔心。

其他有毒動物

吃了會中毒吃：植物有毒（碰或吃會中毒），不是有毒液

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

The cinnabar moth is a brightly coloured day-flying moth with red and black wings. It is native to Europe and parts of Asia, and it has been introduced to New Zealand, Australia and North America. Its bright colours warn predators that it is poisonous.1

有毒還是有毒液？有毒液的動物會用咬或螫把毒液注入身體。有毒的動物則是碰到或吃下去會有害。這種動物是有毒的（碰或吃會中毒）。

首頁

The moth lives where its food plant, ragwort, grows. It was introduced to New Zealand, Australia and North America to control ragwort. Its caterpillars can be seen out in the open during the day, feeding on ragwort.1

長度

2 cm 到 3 cm (0,8 in 到 1,2 in)1

最高速度

大約 9 km/h（5,6 mph）

牠吃什麼？

The caterpillars feed on ragwort, and sometimes on other Senecio plants such as groundsel. They absorb toxic, bitter-tasting alkaloids from the plant, which makes them unpalatable to predators. Large numbers can strip a patch of ragwort clean.1

怎麼認出牠

Predominantly black wings with red patches1
Adults are about 2 cm long, with a wingspan of 3.4 to 4.6 cm1
Often seen flying in daylight, though it is also active at night1
Young caterpillars are pale yellow; later caterpillars are jet-black with orange or yellow stripes1
Rarely, the red can be yellow, the forewing can be all red with a black border, or the wings can be completely black1

毒素力量

吃了會中毒

只有被吃下去時才有害。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

牠害怕時會做什麼？

Its bright red and black colours warn predators that it is unpalatable, and predators seldom eat it.1

如果有人碰了或吃了牠

如果有人吃了牠，或吃了之後出現症狀：立刻打緊急電話或打給毒物諮詢中心。

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。
如果你碰了或吃了牠：不要揉眼睛或摸嘴巴，把手洗乾淨，並且就醫。

牠不是想來抓你。牠的毒只是為了不讓別的動物吃掉牠。更多安全知識

大約跟一根迴紋針一樣長可以在 42 秒內飛過一整座足球場

Cinnabar moth 跟「你」比起來有多大？

牠有多快？

一隻家蠅 大約 7 km/h (4,4 mph)

Cinnabar moth 大約 9 km/h (5,6 mph)

一個正在衝刺的人 大約 37 km/h (23 mph)

值得知道

小知識

The caterpillars can turn cannibalistic, mainly when food is short, and will eat other cinnabar caterpillars.1

Cuckoos are an exception to the moth's protection, as some species eat its hairy, poisonous caterpillars.1

The moth was used as a biocontrol agent against ragwort, working alongside the Tansy ragwort flea beetle in the western United States.1

Very few caterpillars usually survive to the pupal stage, because they can eat their food plant bare before they mature.1

Evidence suggests the Brown long-eared bat preys on this moth.1

The caterpillars overwinter as cocoons on the ground.1
