Outdoor seating in urban areas has become a hallmark of modern city life, offering residents and visitors spaces to relax and socialize. However, its impact on local ecosystems, particularly aquatic insects like stoneflies, is often overlooked. Stoneflies, sensitive indicators of water quality, rely on clean, oxygen-rich streams for their life cycle. The introduction of outdoor seating near water bodies can disrupt their habitat in several ways.

Increased foot traffic and construction near streams can lead to sedimentation, which clogs the gills of stonefly nymphs and reduces oxygen levels. Additionally, runoff from nearby seating areas, contaminated with food residues or cleaning chemicals, can degrade water quality. Stoneflies, which spend most of their lives as nymphs underwater, are highly vulnerable to these changes.

Moreover, artificial lighting from outdoor seating areas can interfere with the nocturnal activities of adult stoneflies, disrupting their mating behaviors. This unintended consequence highlights the need for eco-conscious urban planning. By incorporating green buffers and minimizing pollution, cities can preserve these vital insects while maintaining vibrant public spaces. Understanding these dynamics is crucial for balancing urban development with ecological sustainability.
