About

Michael J. M. Harrap is a behavioral ecologist whose research illuminates the hidden sensory worlds of plant-pollinator interactions. His pioneering work explores how flowers communicate with pollinators beyond color and scent, particularly through floral humidity—the subtle moisture gradients surrounding blooms. His highly cited 2020 study, "Floral Humidity in Flowering Plants: A Preliminary Survey" (35 citations), established that flowers create distinct microclimates through nectar evaporation and transpiration, proposing this as a close-range cue for foraging insects. This foundational work has reshaped our understanding of multimodal floral signaling. Harrap is equally recognized for advancing field methodology; his 2024 paper on "High-resolution outdoor videography of insects using Fast Lock-On tracking" (21 citations) overcomes long-standing limitations in observing bee behavior in natural settings. By enabling high-resolution tracking of tiny, fast-moving insects outdoors, this technique allows researchers to study how bees use vision and spatial memory to navigate complex environments. Harrap’s contributions bridge sensory ecology and technological innovation, offering new tools to decode the intimate conversations between flowers and their visitors.
