Miller Moths

(Pic added Thur 25 Jun 09. Caught one in the screen door in all his ew-icky-yuckness.)

Miller moth season again. Yeah, they get in the house. They like my bright computer screen and sometimes fly in my face.
Ick, ew, yuck.

Googling it...(Colorado has a problem with miller moths, evidently.)

The thing about trying to identify is that all the pics/illustrations show moths with open wings. I never see them that way. When they aren't fluttering around they are sitting with their wings shut and look very dark to black. If I ever get the opportunity, I'll try getting a good pic of one.

"...six of the more common and economically important species of Noctuinae in the Dakotas."

Longer List
Economically Important and Common Moths

Families of Moths
"...about 1,400 species of moths are known from the Dakotas."

One other reference relevant to North Dakota, dated 6 Jun 02.

My abbreviated notes from above link:

Miller Moths are the adult moths of cutworms, Family Noctuidae.

The main species flying around is the Army cutworm, which will migrate to the Rocky Mountains for the summer.

It then returns to the plains in the late summer to lay eggs in fields.

Several migratory moths are also arriving including:
Black cutworm
Variegated cutworm.
Striped cutworm (early Jul)
Red-backed cutworms (mid-Jul)
Dingy cutworms (Jul thru Aug)
Dark-sided cutworm and Bronzed cutworm (Aug-Sep)

Most adult cutworm moths will live about 21 days or more.
