Subspecies E. p. interruptofasciata is sometimes treated as a valid species Eupithecia interruptofasciata.

The forewings are greyish brown with two distinctive black bands. The wingspan is 17–21 mm. The adults fly at night from July to September[1] and are attracted to light.

In the Old World the larva feeds on Juniperus (juniper) and also on some other conifers in the cypress family such as Chamaecyparis and Thuja. In the New World there is a greater range of recorded food plants including apple, clover, raspberry, redcurrant, strawberry, sunflower and willow as well as juniper. The species overwinters as an egg.
