About Eusarca confusaria Hübner, 1813
Scientific name: Eusarca confusaria Hübner, 1813
Identification: This species has a wingspan ranging between 29 and 41 mm. Adult Eusarca confusaria are quite variable in appearance, but typically have a yellow to tan base coloration with gray smudging; some specimens appear exceptionally dark compared to lighter variants. Uncommonly, individual moths have dark spotting in the subterminal area of the forewing. There are several other species that are easily confused with E. confusaria: the dark-edged eusarca (Eusarca fundaria), juniper geometer (Patalene olyzonaria), curve-toothed geometer (Eutrapela clemataria), large maple spanworm (Prochoerodes lineola), and the rose hooktip (Oreta rosea).
Range and habitat: During its flight season, Eusarca confusaria is found across eastern portions of North America, ranging from Nova Scotia in the north south to Florida, and west as far as Texas and Saskatchewan. Within this distribution, the species occurs in meadows and fields where its host plants grow.
Life cycle: There is one annual flight period that runs from April to October across the species' entire range. Larvae of E. confusaria feed on asters, clover, dandelions, and goldenrod.
