Forewings of Alnetoidia alneti: intact and bared with polyvinylsiloxane. (a) Central part of a forewing the left half of which was bared for the purpose of illustration; note that the bare integument appears darker. The partly chipped area (asterisk) is specialized in Typhlocybinae to store a thick layer of brochosomes prior to further distribution across the integument. (b) Bared integument, displaying microtrichia (three protuberances) and vermiculate microsculpture. (c) Intact, brochosome-coated integument. (d) Close-up of (c) showing individual brochosomes.
