Identification

Carrot seed moth is medium-sized snout moth. It is native to Europe, Asia, and North Africa. The first sighting in North America was in Illinois ion 2002. It has rapidly spread since its introduction. In 2008 in was collected in Illinois, Indiana, Michigan, and Wisconsin. It is now well established in North America from Maine to North Carolina west to North Dakota and Missouri, and in Quebec and Ontario Canada. It is still uncommon in Minnesota. Adults are found from June to July in grasslands, gardens, and anywhere else its host species are found. The larva feeds on seed heads of umbellifers, especially Queen Anne’s lace, but also fennel, American cow parsnip, and wild parsnip. It spins a web pulling together flowers within an umbellet. It feeds within the web and later hibernates within it.

Adults are have a slender body, are 716 to ½ (11 to 13 mm) long, and have a wingspan of 1 to 1 (26 to 34 mm). The abdomen is longer than the hindwings, but this is not visible at rest, when both are covered by the forewings. The wings are broad and are held folded flat when at rest. They are usually silky white, sometimes pale yellow or straw-colored, rarely yellow. Regardless of the base color they usually have a faint greenish tint. On the forewing the veins are slightly darkened in the submarginal area and there is usually a patch of dark scales in the median area at the end of the forewing cell.

In my fennel flowers! They seem to create little hide-a-ways to either molt or hide from predators. Possibly both.

In my research, they were discovered along the Great Lakes shipping lanes. It’s non native and was first recorded in Wisconsin on Queen Annes Lace (wild carrot-invasive). Some think it may help curb the spread by keeping the seed heads from dispersing! Can’t decide if I want to keep or rid myself if them. I don't use the fennel for anything but the bulbs and occasion munching of the fronds(myself and Black Swallowtail caterpillars) BUT I don't want them messing with my dill seeds in the future!   carrot seed moth

2016年9月8日午後、山口県萩市見島の農村部で撮影しました。撮影中はシンプルな白い蛾かと思ってましたが、こうして見ると、うっすらと紋様が入っています。この紋様から、本種であると判断しました。

Google translation: Taken in the rural area of Mishima, Hagi City, Yamaguchi Prefecture, on the afternoon of September 8, 2016. I thought it was a simple white moth during the shooting, but when I look at it this way, it has a faint pattern. From this pattern, it was judged that this species.
