The eggs of sweetheart underwing are typically found on the underside of leaves of their host trees, such as oaks and willows. Once hatched, the caterpillars reside on the host plant, camouflaging themselves among leaves and branches to avoid predators.

The adults, being nocturnal, are attracted to light, so to find them, look around light sources after dark or use a light trap. They can also be found resting on tree trunks or walls near their host plants during the day.
