Background and Objective: The different morphological types of sensilla and their distribution on antennae in two species i.e., Creatonotos gangis (Linnaeus) and Creatonotos transiens (Walker) (Arctiidae: Lepidoptera) have been scanned and studied in detail. Materials and Methods: The adult moths of two species were collected from Himachal Pradesh and identified as Creatonotos gangis (Linnaeus) and Creatonotos transiens (Walker) referable to family Arctiidae. After following proper procedure, the SEM Studies were carried out in the Instrumentation Centre, Punjabi University, Patiala. Results: In Creatonotos gangis (Linnaeus), 8 morphologically different types of sensilla had been found on antennae namely sensilla basiconica, böhm’s bristles, sensilla campaniformia, sensilla chaetica, sensilla coeloconica, sensilla quamiformia, sensilla trichodea and uni-porous peg sensilla whereas In Creatonotos transiens (Walker), 5 types of sensilla were present on antennae such as sensilla auricillica, sensilla basiconica, böhm’s bristles, sensilla chaetica and sensilla trichodea. In Creatonotos gangis (Linnaeus) 3 subtypes of sensilla trichodea and 2 subtypes of sensilla chaetica were present whereas, 4 subtypes of sensilla trichodea were found in Creatonotos transiens (Walker). Conclusion: The presence of distinct types and subtypes of sensilla on different parts of antennae in both the species has been examined and it is concluded that their presence is found to be species specific.
