Abstract
Abstract
We examined the effect of substrate moisture on pit construction in Myrmeleon larvae across four treatments (0.0–1.5%). Construction success, pit diameter, and slope angle were quantified using LiDAR-derived morphometrics and analysed via χ² and ANCOVA. Increasing moisture significantly inhibited construction and reduced pit dimensions, with failures restricted to ≥1.0% moisture. These results suggest a critical threshold in substrate suitability, highlighting potential climatic sensitivity within this unique predatory guild.
