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 of a yellow flowered plant. There are 7 currently described species most of which are found in the SW United States and northern Mexico, but Stiria rugifrons makes it into the great plains. All of the species have poorly defined and often overlapping ranges, not to mention the genitalia can highly variable. It’s very likely the final word has not been written about these beautiful noctuids quite yet.
Finally Monday Moth is back =) You have already great stuff out in February!
