Abstract
The common house gecko Hemidactylus frenatus Duméril & Bibron, 1836, preying on the Surinam cockroach Pycnoscelus surinamensis (Linnaeus, 1758), the black soldier fly Hermetia illucens (Linnaeus, 1758), the Dorantes longtail Cecropterus dorantes (Stoll, 1790), the split-banded owl-butterfly Opsiphanes fabrici (Boisduval 1870), a Leuctra satyrid butterfly Taygetis leuctra Butler, 1870, the moth Microthyris anormalis (Guenée, 1854), and the common fungus moth Metalectra discalis (Grote, 1876) is reported for the first time, through photographic records documented between December 2020 and November 2025. The observations occurred in urban areas of Chetumal city, Quintana Roo, Mexico. The prey species involved in this note are evidence of the wide variety of insects that form part of the diet of H. frenatus, particularly in the urban areas it has colonized outside its original geographic distribution.
