Species of moth
Leuconycta diphteroides, the green leuconycta moth or green owlet, is a moth of the family Noctuidae. The species was first described by Achille Guenée in 1852.[1][2] It is found in North America from Nova Scotia to Florida, west to Texas and north to Saskatchewan.[3]
The wingspan is 27–32 mm. The forewings are suffused with green but may be all white in rare cases. There is a small black rectangular blotch which touches the costa near the base and another larger blotch halfway along the costa. One form has a number of black lines and spots scattered across the wing surface, while form "obliterata" is relatively unmarked. The hindwings are pale grayish with a dull yellowish terminal band. Adults are on wing from May to September.
