The first massive outbreak of Metopoplax ditomoides in a natural habitat, observed in March 2025 in Doñana National Park (Spain), was reported. Thousands of individuals aggregated on vehicles and nearby structures, a phenomenon previously known only from winter aggregations in urban or agricultural settings. The event likely resulted from unusual climatic conditions, possibly combined with potential visual or chemical cues. Future monitoring is needed to determine whether this was an exceptional episode or part of a recurrent trend under climate change.
Baena et al. (Tue,) studied this question.
