Identification key to the Noctuinae
occurring in the Dakotas
Below are four possibilities: A, B, C and
D. Compare your moth to each successive choice. These choices are
not always mutually exclusive, proceed to 'B' only if your
specimen does not fit 'A', likewise for B, C, and D.
|
A.
Forewings with patches or streaks of green.*
*Green may fade to yellow or
brownish
yellow in remounted specimens.
|
|
B. Basi-tarsus of meta-thoracic leg with four rows of setae. Thoracic
vestiture of scales.
|
|
|
|
C.
Ptagiae with dark
median line, medial
area, or mostly
dark,
always contrasting
with paler thorax.
|
|
D. Not exactly fitting
other choices (no green, four rows
of setae only if vestiture hairy,
ptagia otherwise colored).
