Abstract:
Although Anomalochrysa maclachlani shares many aspects of its life history and reproductive behavior with other green lacewings, it is atypical in several respects. (i) The preoviposition period is long, and it remains constant at temperatures from 21 through 26.7 °C. (ii) Fertility, which was 100% at 23.4 °C or lower, drops to 16.6% at 26.7 °C. (iii) Females oviposit clusters of about 25 unstalked eggs every 1–7 days, (iv) Both sexes produce loud clicking sounds during courtship; clicking frequently occurs in duet and is associated with anterior-directed flicks of the wings, (v) Females and males may mate repeatedly within several hours. The unusual features of A. maclachlani's reproductive behavior suggest a mode of sexual selection different from that in other chrysopids. Its loud courtship songs and those of other Hawaiian insects (Drosophila, crickets, plant hoppers) represent striking cases of parallel evolution among diverse groups of endemic fauna.
