description Garden tiger moth Overview
The Garden tiger moth (*Arctia caja*) is a large, striking moth found across Europe, North America, and parts of northern Asia. It is recognized by its distinct physical contrast: cream or white forewings with irregular dark patches and bright orange hindwings marked with dark blue-black spots. This bold coloration serves as an aposematic warning to predators, signaling the moth's unpalatable taste due to toxic fluids it can secrete, making it a well-documented species in studies of insect defense mechanisms and environmental adaptation.
help Garden tiger moth FAQ
Why does the garden tiger moth suddenly reveal orange hindwings?
Its patterned cream-and-brown forewings provide camouflage while resting, but the orange hindwings act as a warning display when disturbed. Those bright wings and dark spots advertise that Arctia caja is unpalatable to many predators.
What do garden tiger moth caterpillars eat?
The hairy caterpillars are broad generalists that feed on plants including docks, nettles, brambles, willows, and honeysuckle. They are often called woolly bears because of their dense covering of brown and black hairs.
When can garden tiger moths be seen?
Adults are primarily nocturnal and, in much of Europe, are most often encountered from June through August. The species usually produces one generation each year, with a small caterpillar overwintering in low vegetation.
Why has the garden tiger moth become less common in Britain?
British monitoring has recorded a substantial long-term decline in Arctia caja, despite the species remaining widespread across its broader Holarctic range. Research has linked its vulnerability to changing land use and to warm, wet winters and springs.
