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

Leef in

Found throughout mainland Australia1

Australië & Oseanië

Tuis

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

Wat eet dit?

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

Hoe om dit te herken

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

Gifkrag

Brandhare

Piepklein haartjies of borsels breek in die vel af en brand.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

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

Wat doen dit as dit bang is?

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

As jy aan sy hare raak

Vir ruspe-brandhare: lig hulle af met kleefband en was dan die vel. Moenie vryf nie.
Vir byte: was en koel af. Kry mediese hulp as die persoon sleg voel of maklik bloei.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As jy aan sy hare raak: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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
