Porch Light Moths (2): While it is not 100% understood why moths are attracted to lights, for those of us who appreciate their beauty, it’s an easy way to attract and observe them. At first glance, these two moths (in the family Noctuidae) might appear similar …but take a look at the subtle, but intricate, patterns and differences in appearance and you quickly see you are looking at 2 different species. Photo 2: Dichagyris variabillis — these moths fly from late July into October and tend to be found in dry open ponderosa pine forests and in juniper woodlands.
