Identification
One of the largest species in the group. The specimens from Arizona to Texas have only dots for a postmedial line and the northern population has a bolder solid line. When the median line is visible it converges with the postmedial line near the inner margin. The Rindge description of the abdomen does not mention distinct black and white banding of segments for this species, but does specifically mention this banding for G. quinquelinearia and describes the abdomen of mcdunnougharia as similar to that of quinquelinearia. Rindge states this prominent black and white abdominal banding is lacking in previously described Group III species including interpunctata. (1)
Description by Sperry (1952) specifically mentions lack of black and white banding on the abdominal segments as a characteristic to separate interpunctata from quinquelinearia and mcdunnougharia. (4)
Range
Arizona to western Texas, north to Utah and Colorado (1)
Season
mid-April to early September (1)
Food
Larval foodplant in the Arizona, New Mexico, and Texas is alligator juniper, Juniperus deppeana Steud. (1)
See Also
Glena quinquelinearia is similar but has distinctly banded abdomen and the median line does not tend to converge with PM line toward inner margin. It is limited to Texas and New Mexico. (1)
Glena macdunnougharia is also similar and its range largely overlaps the range of interpunctata, however it is described by Rindge with a distinctly banded abdomen and its median line does not tend to merge with the PM line toward the inner margin. (1)
