Carabidae and Cicindelidae collected from January to December in 1985 by a number of different collecting methods in the Dumoga?Bone National Park area of N. Sulawesi (Indonesia) were examined to assess their reproductive seasonality. The state of gonad maturity was assessed through dissection of 5099 specimens, representing 203 species of Carabidae and 15 species of Cicindelidae. For the Carabidae, 45.7% of females and 12.0% of males were 'immature' (non?reproductive). For the Cicindelidae the corresponding figures were 38.7% and 18.5%. In carabids the peak month for immatures is July and this corresponds with the highest percentage of females that are post?reproductive (as evidenced by the presence of the corpora lutea). A similar but less pronounced trend is found in male carabids. The proportion of immatures varies less in cicindelids during the year. Analysis of data for carabids from different habitats and lifestyles (leaf litter, dead wood and under bark, fossorial, riparian, grass/marsh, log?runners, leaf?runners, and termitophiles), suggests that different guilds have different patterns of reproductive seasonality. Furthermore, the reproductive seasonality may differ between species within these guilds. The effects on reproductive seasonality of the considerable local variation in climate in the study area and of sampling at different altitudes and with a range of collecting methods are also considered. 15 pp., 3 figs, 11 tabs, gr. 8.
