A general term for insects in the Hemiptera, Heteroptera, Tingidae family. Small, flat, terrestrial stink bugs, most of which are 2.5-4.5 mm long, with even the largest measuring less than 8 mm. The head is small and lacks an eye. The antennae have four segments, with the third being the longest. The pronotum and forewings are finely net-like. The English name is derived from this feature. The pronotum usually has a cap-shaped area in the center of the front, wing processes on the lateral edges, and three vertical ridges on the posterior half. The forewings are transparent or opaque membranous, lack leathery areas, and are folded horizontally. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
