Small Yellow Underwing
There are a few related species similar to this dainty little moth, although it is distinguished from these by its generally darker and more unicolorous forewing with the single conspicuous golden yellow spot.
There are two generations, occurring from mid-April to June and again from July to mid-September. It has also been found in mid-March and sometimes into early October. Flies actively in sunshine and also at night. During the day adults are often found sitting on the leaves of Mint or related species.
