Based upon adults reared from dead wood collected in Connecticut and nearby states, larval hosts for 58 species of Cerambycidae in the subfamilies Parandrinae, Prioninae, Lepturinae, Spondylidinae, and Cerambycinae are reported. New hosts were discovered for 34 (58.6% of total) of the species. In all, 1,892 adults were reared to document 170 host associations, including 87 (51.2% of total) new host plant records. Neoclytus acuminatus acuminatus (Fabricius) had the broadest host range with 30 fully identified hosts, followed by Xylotrechus colonus (Fabricius) with 13 hosts; the remaining 56 species developed in seven or fewer hosts. Cerambycid adults emerged from 62 woody species in 33 genera distributed among 20 plant families. The number of known host families for each species usually is given, along with comments about questionable host records. Evaluation of host records and suggestions for improved reporting are discussed.
