[3] Adults overwinter in leaf litter and emerge early in spring to feed on leaves and mate.

[4] Female R. latipes lay eggs preferentially on the compact flowering head of the plant, a tender location that allows larvae to easily bore into the stem.

Stem boring and internal feeding by larvae significantly reduces the growth and reproductive ability of P. perfoliata.

[5] Fully grown larvae drop into the soil to pupate and emerge as adults by climbing up nearby stems, approximately one month after egg laying.

Originally from Asia, Rhinoncomimus latipes was intentionally introduced in North America in 2004 to control mile-a-minute, which is invasive in several Northeast US states.
