Interpretive Summary: The caterpillar-like larvae of sawflies are all plant feeders, and many can be of economic importance in forests, agricultural crops, and ornamental plantings. The host plants of only about a quarter of the North American sawflies are known. New host records are given for eight species, together with some biological notes and description of the larvae. New host plants include serviceberry, starflower, oak, poplars, asters, hop hornbeam, and anemone. This will be of interest to researchers interested in plant-feeding insects and will help identify sawfly larvae found on these plants.

Technical Abstract: We present the first larval host records for the sawflies Sterictiphora sericea (Norton) (Argidae), Ametastegia aperta (Norton), and Macrophya flavolineata (Norton) (Tenthredinidae). New records are presented for six other tenthredinids: Caliroa lobata MacGillivray, C. lorata MacGillivray, Fenusella populifoliella (Townsend), Nematus corylus Cresson, Profenusa lucifex (Ross), and Pseudodineura parva (Norton). Larvae are described and illustrated for all of the non-leafmining species. The ichneumonid parasitoids Lathrolestes sp. and Erromenus ungulatus Townes & Townes were reared from C. lobata and P. parva, respectively.
