New larval host plants and ecological observations on North American Cerambycidae (Coleoptera)

New larval hosts are presented for 152 North American Cerambycidae (Coleoptera). Larval host plants of Aneflus calvatus Horn in Leng, Aneflomorpha arizonica Linsley, Aneflomorpha fisheri Linsley, Ane­flomorpha opacicornis Linsley, Anelaphus magnipunctatus (Knull), Atylostagma glabra Schaeffer, Cacophrissus pauper Bates, Elytroleptus limpianus Skiles and Chemsak, Obrium rubidum LeConte, and Stenelytrana splen­dens (Knull) are reported for the first time. The types of wood utilized by larvae of Leptorhabdium pictum (Haldeman), Sphenostethus taslei (Buquet), Typocerus lugubris (Say), and Xestoleptura octonotata (Say) are discussed. Notes on larval morphology and larval habits of Aneflus spp. and Stenaspis solitaria (Say), includ­ing a correction of a published host plant record for S. solitaria, are provided. Urgleptes sandersoni Gilmour is reported from the United States (Florida) for the first time. The family Cerambycidae is a diverse group of wood boring beetles with over 1000 species in North America alone and tens of thousands worldwide. Host plant associations for North American Cerambycidae have been summarized by Linsley and Chemsak (1997) and many subsequent papers have provided additional information (Swift 2008; Vlasak 2014; Heffern et al. 2018; Maier 2018; Maier 2020 and references therein). Several recent publications attempted to correct erroneous records in the literature and highlighted some questionable ones (Bousquet et al. 2018; Heffern et al. 2018; Maier 2018; Maier 2020). Nevertheless, the biology of about 180 North American species remains unknown and the understanding of host plant associations overall is incomplete. This work is a continuation of efforts to further the knowledge of the natural history of Cerambycidae. Only host plants not previously reported in the literature (summarized in Table 1) are presented unless stated otherwise. Plant taxonomy follows that of Kartesz (2015)
