Scatrina Pooping Outdoor May 2026
Across all sites, Scatrina pooping peaked during the first two hours after sunset (20:00–22:00 h), accounting for 68 % of recorded defecation events (Fig. 1). A secondary, minor peak occurred between 02:00–03:00 h (12 %). No significant differences in timing were observed among the three fragments (KDE overlap = 0.94).
The genus Scatrina (Order Coleoptera, Family Scatrinidae) comprises a group of nocturnal, arboreal beetles endemic to the low‑land rainforests of the Western Ghats. Despite extensive research on their foraging and reproductive strategies, little is known about their excretory behaviour in natural settings. This study documents the spatial patterns, temporal rhythms, and ecological consequences of Scatrina outdoor defecation (“pooping”) across three forest fragments (30 ha, 45 ha, and 60 ha). Using motion‑activated camera traps, fecal pellet counts, and stable‑isotope analysis, we show that Scatrina preferentially deposit feces on the undersides of broad‑leaf saplings within 1 m of their perching sites, primarily during the first two hours after sunset. The fecal deposits are rich in nitrogen (average 2.8 % N dry weight) and phosphorus (0.42 % P), contributing significantly to the nutrient pool of the leaf‑litter layer. We also demonstrate that these deposits attract a distinct assemblage of detritivorous micro‑fauna, thereby enhancing micro‑habitat complexity. Our findings suggest that Scatrina outdoor pooping is a non‑random, ecosystem‑engineered behaviour with measurable impacts on nutrient cycling and forest floor biodiversity. Management recommendations include preserving understory sapling diversity to maintain these ecological processes.
Temporal activity patterns were examined using kernel density estimates (KDE) in the “activity” package (R 4.3.1). Spatial clustering of feces was assessed with Ripley’s K‑function. Nutrient concentrations were compared across sites using one‑way ANOVA, followed by Tukey’s HSD. Relationships between fecal density and detritivore abundance were explored with linear mixed‑effects models (lme4 package), with site as a random factor. Significance was set at α = 0.05.

Research was conducted in three protected forest fragments within the Western Ghats, India (Table 1). All sites share a monsoonal climate (mean annual precipitation ≈ 2200 mm) and a mixed evergreen–deciduous canopy.

Excretion is a fundamental physiological process, yet its ecological ramifications are often overlooked, especially in invertebrates (Mason & Lee, 2015). In forest ecosystems, the spatial distribution of animal waste can affect nutrient hotspots, micro‑habitat structure, and the dynamics of decomposer communities (Harmon et al., 2012). The beetle genus Scatrina is notable for its cryptic lifestyle, high population densities, and pronounced nocturnal activity (Patel & Rao, 2018). Preliminary observations indicated that individuals frequently defecate on the undersides of saplings while perched, prompting speculation that this behaviour may have ecological significance.
The present study aims to (i) characterise the temporal and spatial patterns of Scatrina outdoor pooping, (ii) quantify the nutrient content of their feces, (iii) assess the influence of fecal deposits on detritivore assemblages, and (iv) discuss implications for forest management. By integrating behavioural observations with chemical and community‑level analyses, we provide a comprehensive account of a previously undocumented ecological function.
