One-Spotted Variant (Hypagyrtis unipunctata) lives in moist woodland across Eastern North America. It feeds on lichens and leaves.
Fascinating facts about the One-Spotted Variant
- In 1809 Adrian Hardy Haworth gave science its first glimpse of this tiny night-flyer, naming it Hypagyrtis unipunctata. Belonging to the Geometridae family, the moth carries a single white spot that inspired its common name, one-spotted variant moth.
- Adult one-spotted variant moths take to the air from April through September across most of North America, but in the cooler northern zones they limit their flight to June and July. Within a single year, populations can produce one to two generations.
- From the Atlantic coast of Nova Scotia all the way to Florida, westward to Texas, and northward to British Columbia, this moth also crosses the ocean to inhabit parts of Eurasia.
- Caterpillars of the one-spotted variant moth munch on the leaves of a long list of deciduous trees and shrubs, from Amelanchier and Rosa to Quercus and Acer, showing a truly generalist feeding habit.
- First spotted by a British naturalist in 1809, this moth now blankets a continent from the Atlantic shores of Nova Scotia down to Florida, stretches westward to Texas, reaches the Pacific edge in British Columbia, and even hops across to Eurasia. Its broad distribution shows how a tiny winged insect can thrive in vastly different climates, linking ecosystems thousands of kilometres apart and reminding us that even modest species can be global travelers.
