Bag-shelter moth

Ochrogaster lunifer

名字的由來： The caterpillars are called processionary caterpillars because they travel in single file, and bag-shelter because they live in silk bag nests.1

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The bag-shelter moth is a moth whose caterpillars live together in silken bag nests and march in long lines. Its hairs can cause skin rashes, so it matters to anyone who lives in or visits mainland Australia.1

Caterpillars shelter during the day in silken bag nests on branches, high on trunks, or at the base of their food plant. They feed on acacia (wattle) trees and Grevillea striata (beefwood). In autumn, the mature caterpillars travel in long single-file processions to find places to pupate.1

牠吃什麼？

Caterpillars feed on the leaves of acacia (wattle) trees and Grevillea striata, mostly at night after the early stages. Adult moths do not feed, as their mouthparts do not work.1

怎麼認出牠

Adult moths have a woolly appearance and wings up to 5.5 cm across.1
Forewings are dark grey or brown. Hindwings are white, shading to grey at the base.1
Some moths have a pale dot in the centre of each forewing, and some have white lines across the wings.1
The abdomen is banded and ends in a white tuft of hairs.1
Caterpillars live in brown silk bag nests by day and feed at night, moving in single-file lines.1

會螫人的毛

細小的毛或刺毛會斷在皮膚裡，造成刺痛。

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。

The hairs on the egg masses, caterpillars and adult moths can cause irritating skin rashes (dermatitis) in humans and other animals. Records also list osteomyelitis, eye inflammation (ophthalmia) and more severe allergic reactions. In horses, eating the caterpillars may cause pregnant mares to abort.1

牠害怕時會做什麼？

When disturbed, caterpillars curl up into a tight bunch, and their loose hairs can be carried away on the wind.1

如果你碰到牠的毛

被會螫人的毛毛蟲毛刺到時：用膠帶把毛黏起來，再清洗皮膚。不要搓揉。
被咬時：清洗並冷敷。如果傷者覺得不舒服或容易流血，要就醫。

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。
如果你碰到牠的毛：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

值得知道

小知識

The final caterpillar stage carries more than two million urticating hairs (setae).1

A procession can contain a hundred or more caterpillars, each one holding onto the tail hairs of the one in front.1

Caterpillars follow silk trails left by others, and if two meet on each other's trails they can walk in a circle, sometimes forming a large circular mass.1

Females cover their eggs with scales from the tuft at the end of their abdomen to protect them from predators.1

The whole life cycle takes one year, and the caterpillars live together as a group from egg to pre-pupa.1
