1We examined behavioral responses of the field cricket Gryllus bimaculatus to tactile stimuli 2 to the antennae. Three stimulants of similar shape and size but different textures were used: a tibia 3 from the hunting spider Heteropoda venatoria (potential predator), a tibia from the orb-web spider 4Argiope bruennichii (less likely predator), and a glass rod. Each stimulus session comprised a first 5 gentle contact and a second strong contact. The evoked behavioral responses were classified into four 6 categories: aversion, aggression, antennal search, and no response. Regardless of the stimulants, the 7 crickets exhibited antennal search and aversion most frequently in response to the first and second 8 stimuli, respectively. The frequency of aversion was significantly higher to the tibia of H. venatoria 9 than to other stimulants. The most striking observation was that aggressive responses were exclusive 10 to the H. venatoria tibia. To specify the hair type that induced aggression, we manipulated two types 11 of common hairs (bristle and fine) on the tibia of the predatory spider. When bristle hairs were 12 removed from the H. venatoria tibia, aggression was significantly reduced. These results suggest that 13 antennae can discriminate the tactile texture of external objects and elicit adaptive behavioral 14 responses. 15 16

An overview of larval antennal sensilla in hemimetabolous and holometabolous water-living insects is given by updating current knowledge on the fine structure of these sensory systems. In the absence of successful electrophysiological studies, the possible function of sensilla is deduced from their architecture. Various kinds of sensilla are described in hemimetabolous insects, such as Ephemeroptera, Odonata, and Plecoptera, and holometabolous insects, such as Diptera Nematocera (Culicidae, Simuliidae, Psychodidae, Chaoboridae) and Trichoptera. Their possible function in responding to stimuli from the freshwater environment is illustrated and discussed. The importance of sensilla as taxonomic and phylogenetic traits is reported in Baetidae (Ephemeroptera) and in Diptera Nematocera. Some homologies outlined in Diptera Nematocera give evidence of a link between species, such as Chaoboridae and Psychodidae, whose antennae are highly modified, prehensile in the former and very reduced in the latter. Particular features, such as cuticle without pores in chemosensory sensilla and naked perikarya, are so far found exclusively in some water-living arthropods, thus reflecting a possible adaptation to the aquatic habitat. The structure of sensilla and chloride cells, which have a similar external morphology, is presented and discussed in various insect groups, considering the possible derivation of the chloride cells from sensilla.
