In the northeastern United States, at least nine species of Cerambycidae infest native and introduced woody plants in the family Cupressaceae. Their general biology, including emergence, seasonal catch on sticky bands on hosts, and/or hosts (based on rearing), were examined in New England, New York, and New Jersey, between 1998 and 2005. The period of emergence, seasonal abundance, and/or hosts are presented for Atimia confusa, Callidiellum rufipenne, Callidium frigidum, Callidium violaceum, Oeme rigida, and Semanotus ligneus. The new biological information is particularly important for Callidiellum rufipenne, an eastern Asian beetle of regulatory concern.
