For this Monday’s Moth I thought I’d post a brief tutorial on how to accurately determine the sex of moths. While there are lots of examples of sexually dimorphic species (where males and females are obviously different), the vast majority of moths are not. Saturniidae make our lives easy by having strikingly different antennae between . . . → Read More: How to Sex a Moth
Today’s moth is a beautiful species from the Rocky Mountains outside of Denver, Epermenia stolidota (Epermeniidae). This is actually a larger specimen than it appears, about 20mm from wingtip to wingtip. Those raised, darkened, tufts of scales on the posterior edge of the forewing is a great character for this . . . → Read More: Monday Moth
This week I’m sharing a tiny, scruffy, and semi-competently spread Nepticulidae in the genus Stigmella from the same light trap of Prescott Arizona as the past few Monday Moths. I usually wouldn’t share a photo of a moth that isn’t in the best condition, but I’m using this as an example of . . . → Read More: Monday Moth
How about another unidentified Gelechiidae from the same location as the previous specimen (nr. Prescott Arizona). I’m taking a stab at this moth being in the genus Chionodes – and it is superficially similar to the species C. continuella. Thankfully there is a monograph of this group (Moths of America North of Mexico, fascicle 7.6) . . . → Read More: Monday Moth
This moth is a good example of what a lot of my moths are at the moment – unidentified! This is certainly a Gelechiidae, you can see the large upturned palps on the front of the head, and a finger-shaped projection on the tips of the hindwings. Just about one of the easiest . . . → Read More: Monday Moth
Today’s moth is a stunning micro and another creature from Barb Bartell’s back yard in the Rockies. To the best of my knowledge it’s a species of Mompha (Coleophoridae), probably claudiella,but I don’t have a positive ID on this bug yet. Once I start digging through the micros from this site there are sure to . . . → Read More: Monday Moth
To reignite the Monday Moth series here is a stunner: Melemaea magdalena (Geometridae).
This rare beauty has previously only been known from scattered localities across the mountain west and only from a few individuals every other season. That is until Denver Museum volunteer Barbara Bartell began inventorying moths on her property near Golden Gate . . . → Read More: Monday Moth
A Monday moth in fuzzy pink – Dryocampa rubicunda (Saturniidae). These rosy maple moths are pretty common in southern Illinois, but always a stunner when they come to light.

Today’s moth is an understated brown Crambidae, Loxostege brunneitincta. While this isn’t a particularly captivating moth it does have an interesting story that illustrates the need for scientific collections and museum loans. If you read the label image you will notice the moth was originally collected in 1927 by E. P. Van . . . → Read More: Monday Moth
Back to the Monday Moth! This beautiful insect is Stiria dyari (Noctuidae) collected on a February trip outside of Cataviña, Baja California Mexico. I believe the host plants are still unknown, but all of the moths in the genus Stiria have these brilliant yellow forewings that help camouflage them on the stem . . . → Read More: Monday Moth
