The garden tiger moth or great tiger moth[2] (Arctia caja) is a moth of the family Erebidae. Arctia caja is a northern species found in the US, Canada, and Europe.[2][3] The moth prefers cold climates with temperate seasonality, as the larvae overwinter,[3] and preferentially chooses host plants that produce pyrrolizidine alkaloids.[4][5][3] However, garden tiger moths are generalists, and will pick many different plants to use as larval host plants.[5][4][3]
