Abscondita anceyi

Biology. Jeng observed in Taiwan that both Abs. chinensis and Abs. anceyi flied high, usually over, on or just below tree canopy in forests. Males produced flash trains in flight, about 9 – 11 quick flashes in 1 – 1.5 sec, followed by a long silence of several seconds (these observations were made with the naked eye). Females of chinensis also flew high in mating course, but they were more commonly seen flying low to lay eggs later in the season. Females of both chinensis and anceyi produced continuous glow after mating, since such bioluminescent display was more common in the late but not at the beginning of the season. In general, it is not difficult to determine which is which by their habitats as well as male flash patterns in the field. However, this is not the case in those areas in mainland China. In Mt. Emei (Sichuan Province) after dark, males and females usually flew to top of bamboos for courtship. Females produced a long glow signal when they were flying to the top of bamboos (Fig. 4 B). Males produced fast single flashes when they were flying on the top of bamboos with flash duration 209.6 ± 86.4 ms (n = 14; mean ± sd) and interval 465.6 ± 160.1 ms (n = 14; mean ± sd) (Fig. 4 A). Females produced single flashes when they were flying on the top of bamboos with duration 548.6 ± 57 ms (n = 7; mean ± sd) and interval 850.7 ± 23.2 ms (n = 7; mean ± sd) (Fig. 4 C).
