Insects (other than moths) attracted to light that were abundant on expressways. A substantial number of common chafers were attracted to blue light and trapped in the basin (a, b). Note that two Arctiid moths (Chionarctia nivea) were intermixed with the chafers (b). Aquatic insects, including caddisflies (Stenopsyche marmorata) (c) and dobsonflies (Protohermes grandis) (d), were attracted to any light sources with a sufficient intensity. Unidentified winged ants were attracted not only to the UV LED (e) but also to red light (f) illuminated on the ground. Scale bars = 2 cm in b, e, f, 1 cm in c and d
