- Summary:
- Among insects, the incidences of wing reduction and loss of flight tend to increase at high altitudes. This also occurs on isolated landmasses that are surrounded by inhospitable terrain or water. Therefore, it is not surprising that numerous remarkable cases are found among the endemic radiations of alate insects that colonized the Hawaiian Islands. Of the five flightless species of Micromus that are known to be from the Hawaiian Archipelago, only one, the rare Micromus usingeri, is reported to be from the Island of Hawaii. As a result, the natural occurrence of intermediates between this brachypterous species and its near relative, the macropterous Micromus longispinosus, are reported here where some of the morphological and life-history characteristics of the two species and the intermediates are compared.
