Agelenopsis potteri
Potter's Grass Spider
A funnel-web spider native to North America that has been introduced to Ukraine, Russia, Kyrgyzstan, and China. It is easily identified by structural features and has established stable breeding populations in urban environments across 19 of 25 Ukrainian administrative regions as of 2025. The species exhibits typical summer-autumn phenology with adult activity peaking in August and September. Unlike many spiders, it cannot disperse via aerial ballooning and spreads through human-mediated transport.
