Olfactory sensilla show a large diversification of sensillum types even in the same species. Thus, double-walled and single-walled sensilla with highly different wall pores are usually found on the same antenna, and these may appear in the form of long slender hairs, pore plates or pit pegs. The selective constraints leading to this diversification are evident only in a few cases, e.g. the demand for extreme sensitivity in moth pheromone communication supported the evolution of long sensilla… CONTINUE READING
