Abstract

By scanning and transmission electron microscopy, blunt-peg type of sensilla (sensilla basiconica) were found on the tarsus of the 1st leg of Macrocheles muscaedomesticae (Scopoli). The changes in number, size, and position were determined for each life stage. The number of blunt pegs in the larva, protonymph, deutonymph, and adult stages were 6, 7, 8, and 8, respectively. Similar sensilla were not found on the terminal segment of the palps.
