pass through five instars (developmental stages) over the course of three to five weeks. The first instar lives underground after which the nymph climbs the host plant. The nymphs are largely red but in the fourth and fifth instars, the dark wingpads are apparent as they enlarge, and the abdominal segments develop pale margins and become more obvious. There are several generations each year.

Biology

The adults and late stage nymphs feed on the protein-rich seeds of their host plants. As these become available at different times of year, the winged adults migrate between different plant species. The adults have also been observed
