Male Rajah Brooke's birdwings (Trogonoptera brookiana) commonly form daytime puddling aggregations on mineralized riverbanks, hot springs and seepages.
Aggregations can be long-lived at stable springs and range from a few individuals up to several hundred males, making these sites the best opportunity to observe and photograph the species.
