PLATE 1.18. QUEEN WING BASES

MIDDLE Wing base detail (the head is to the left). Numerous proprioceptors are evident on the various sclerotized pleural plates adjacent to the wing bases. The function of the pores that are visible is not known. (x 85)

TOP LEFT Pleural region beneath the hind wing. Many branched hairs emanate from sockets. (x432)

TOP RIGHT Higher magnification of shallow pores in the cuticle. (x 4,400)

BOTTOM LEFT. Wing sclerite with branched, acutely tipped body hairs and relatively short trichoid sensilla. The sensilla may be innervated and if so might serve as external proprioceptors. Pores are visible along the trailing margin. (x 360)

BOTTOM RIGHT Sheared trichoid. An apparent lumen is in the hair shaft. (x 5,500)
