Abstract Insect diversity levels and change in remnant urban habitats have been poorly examined in Neotropical regions. The aim of this study was to evaluate the diversity and composition of foliage/shrub dwelling beetles (Insecta: Coleoptera) regarding the influence of patch attributes (i.e., patch size, connectivity, and surrounding matrix) and within-patch habitat complexity, in an urban landscape at Chetumal, Yucatán peninsula, Mexico. Despite the potential species-specific responses to urban landscape pattern, our study reveals that there are effects of patch spatial features and habitat complexity on overall beetle diversity.These effects are as follows: 1) relatively larger urban patches contained higher overall beetle richness, 2) beetle species composition varied significantly regarding understory vegetation structure and tree richness, and 3) patches of intermediate vegetation age had highest beetle richness.This research provides a case study of patch and habitat features related to Neotropical insect assemblages in urban settlements, underlying the importance of using ecological information to offer management recommendations in ever-expanding urban tropical settlements.
