This moth was on the side of our cabin at the C Lazy U guest ranch near Granby Colorado.
Beautiful, vibrant colors – it hung out all afternoon prior to a rain storm.
The Great Tiger Moth or Garden Tiger Moth, Arctia caja, is a holarctic species, meaning it is found in Eurasia as well as North America. According to BugGuide: “This species, formerly common throughout the UK, has steadily declined over the past 20 years, with numbers falling by around 30%. There has been a general movement away from the south and toward the north, with climate change believed to be a contributing factor. Warm, wet winters and warm springs are followed by a decrease in the number of tiger moths the following summer (Conrad et al, 2002).”
