1. Seasonal or annual population fluctuations have been reported for various tropical insect species, exhibiting one or more peaks in abundance at certain times of the year. Such fluctuations have mostly been observed in areas that experience annual wet and dry seasons, and not in areas where climatic fluctuations are unpredictable on an annual basis.2. This study attempted to evaluate the extent of seasonality in population fluctuations of a light-trapped chrysomelid assemblage consisting of 25 Garelucinae and one Eumolpinae in a Bornean rainforest that is characterised by an aseasonal climate.3. This study also attempted to test the effects of short-term rainfall changes and leaf-flushing phenology on chrysomelid population fluctuations.4. The majority of the chrysomelid species showed one or more abundance peaks that were unrelated to season.5. The population fluctuations did not correspond to short-term fluctuations in rainfall or leaf-flushing phenology, although these environmental factors somewhat correlated with each other and fluctuated irregularly.6. These results suggest that populations of most chrysomelids fluctuate aseasonally and that short-term fluctuations in rainfall and leaf-flushing phenology hardly affect population fluctuations in Bornean rainforests where seasonal climate patterns are weak.

1. Seasonal patterns in insect population fluctuations have rarely been examined in rainforests of the central part of Southeast Asia where the climate is aseasonal.2. We examined the seasonality of population fluctuations in a Bornean rainforest phytophagous scarabaeid assemblage (six species of Melolonthinae and seven of Rutelinae). We also investigated effects on abundances of these insects of irregularly fluctuating environmental changes, such as short-term rainfall, and community-level leaf flushing and flowering of canopy trees. Scarabaeids were collected over 6 years by monthly light-trapping.3. Eight scarabaeid species had clear seasonality in occurrence and abundance. Seasonal trends were synchronised across the eight species; their monthly catches peaked from March to May and were nearly zero in other months. An analysis of correlations between environmental changes and insect abundances suggested that short-term changes in rainfall affected the synchrony.4. In contrast, fluctuations in abundances of five other scarabaeid species were unrelated to calendar seasons. In one of the five scarabaeids, which is a flower-visiting species, the patterns in population fluctuation strongly correlated with flowering changes. In the remaining four species, no correlations were observed between environmental changes and population fluctuation patterns.5. While previous studies have demonstrated that aseasonal patterns in population fluctuations are common in various insect assemblages in Southeast Asian rainforests, we show that clear seasonality is prevalent for the phytophagous scarabaeid assemblage.
