From: Evolution, types, and distribution of flight control devices on wings and elytra in bark beetles
Distribution of various types of flight-related mechanosensors on hind wings and elytra of bark beetles: (a) campaniform sensilla fields, (b) wing margin trichoid sensilla, (c) isolated trichoid sensilla, (d) isolated campaniform sensilla, (e) Lehr’s field (campaniform sensilla field located on the root of elytra). SEM images are given on the left side, and optical microscope images are given on the right side of each magnified picture. The dotted line indicates transverse wing fold. Yellow areas indicate the location of two small MS fields that have not been analyzed (see “Materials and Methods”). Other colored areas indicate regions where a particular type of mechanosensor might be distributed. Abbreviations: C—Costal edge (leading edge), RA—Radius Anterior, Cu—Cubitus/Cubital Vein, AA3+4—Anal Anterior (branches 3 and 4), CAS—Cubitoanal Strut (Cu + CuP + AA3), MP1+2—Media Posterior (branches 1 and 2), MSP—Medial Spur (continuation of MP1+2), SS—Support Sclerite, MJ—Marginal Joint, RP3+4—Radius Posterior (branches 3 and 4), RP1+2—Radius Posterior (branches 1 and 2).
