Life Cycle of Birch Catkin Bug
Egg The egg stage finds the birch Catkin Bug developing embryonically. The eggs are often oviposited in a secure, concealed location, with color and size specific to the species. They remain static until hatching occurs.
Nymph Upon hatching, the nymph resembles a miniature adult birch Catkin Bug, lacking fully developed wings and reproductive organs. As it grows, it molts several times, increasing in size and gradually developing wing pads and adult-like features.
Adult Emerging from the final molt, the adult birch Catkin Bug exhibits fully developed wings and reproductive organs. The body is now fully formed and hardened, and the adult is mobile, focusing on mating and laying eggs for the next generation.

As adults, they often relocate to stems and branches, assuming a more conspicuous position likely due to increased mobility and the ability to escape predators quickly. To find these stages, thoroughly inspect leaf surfaces and crevices among seeds and fruits for nymphs, while scanning stems and branches for adults, particularly on or near host plants, including various grasses and weeds.

Hurt Plant

When birch Catkin Bug feeds on birch and alder tree seeds, it punctures the seed coats and extracts vital fluids. This mode of damage can result in the disruption of nutrient flow within the seeds, potentially hindering their germination and growth. The long-term effects may include reduced seed viability and compromised natural rejuvenation of these tree species.
