scientific name    Chrysoteuchia topiarius    

common name     Cranberry Girdler

Native and tame grasslands.

Late June to early August.

A small crambid (17-20 mm wingspan). The forewings vary from dark (clay colored) to light yellowish brown, lack a silvery white longitudinal median stripe, often have clearly marked dark fuscous veins, have a prominent angled silvery gray subterminal line, have 3 black dots at the bottom of the terminal line, and have a fringe of shiny bronze scales. The hind wings are gray and lack prominent venation. Formerly called Chrysoteuchia hortuellus topiarius. Similar to the common European species Chrysoteuchia culmella, but smaller. Can be mistaken only with Platytes vobisne which is tiny (12-13 mm wingspan) and has zigzag postmedial and subterminal lines.
