Douglas-fir spittlebug

Forests and Woodlands, Grasslands and Prairies, Agricultural and Cultivated Areas

The eggs of douglas-fir spittlebug are typically laid on the underside of host plant leaves or on stems, thus search efforts should focus on inspecting these areas. The nymphs, undergoing incomplete metamorphosis, reside primarily on the host plants, hiding under bark or within plant tissues. They're particularly associated with herbaceous vegetation and young woody plants, where sap is readily accessed. Adult douglas-fir spittlebug frequent the same vegetation as the nymphs, but are fully winged and mobile, often found on leaves or stems, and can also be spotted around meadows or edges of bodies of water. To locate them across these stages, one would carefully examine the host plants, checking beneath leaves, around stems, and in crevices close to the ground.

The best time to locate douglas-fir spittlebug is usually during their active months, which can vary depending on the climate. Generally, searching during warmer parts of the day like late morning or early afternoon may increase the chances of encountering active douglas-fir spittlebug.

Dry and warm weather conditions are ideal for finding douglas-fir spittlebug. Excessive rain or cold may cause the creature to be less active or to seek shelter, making them harder to locate.
