Insects are less predictable and more ephemeral in the wet season, and bats scale-up temporal foraging effort accordingly. Overview and summary metrics of temporal and spatial insect distribution and bat foraging effort. In the wet season on average, (A) insect abundance is almost 75% lower, (B) largest insect peaks are nearly 50% lower, (C) instances of no insect availability are over 5x more common, (D) insect patches (≥10 insects per photo) are over 2x rarer, and (E) insect patches are more ephemeral, persist for almost 15 min less. Bats in the wet season on average, (A) forage almost 45% longer, (B) emerge 12 mins earlier relative to sunset (45%), (C) feed 30% shorter in each insect patch and search nearly 70% longer for the next insect patch, (D) spend the same total amount of time in ARS-feeding, but (E) spend more time commuting-searching in total, (F) decreasing the proportion of ARS-feeding by nearly 25%. Overview plot: lines represent insects detected in photos (every 5 min) over the night per platform for single nights of monitoring at identical locations during the wet (N=31) and dry seasons (N=22). Horizontal bars represent foraging bouts of individual bats, for each date they were tracked, colored by behavioral state: light colors represent commuting-searching and dark colors, ARS-feeding. N=23 foraging bouts in the dry season and N=48 foraging bouts in the wet season. For insect summary metric plots, each point represents a calculation (A-C, E) per photo for one of the same four locations between seasons or (D) for photos across all locations, on each monitoring night. For bat summary metric plots, points represent (A-B, D-F) each night of tracking for every bat, or (C) a segment of a behavioral state within a bat’s track. Diamonds represent bootstrapped means and bars represent bootstrapped 95% confidence intervals around means.
