Alejandro Avellaneda — Villa Tacú — San Juan

Official source account — 2021 annual report, printed page 82: Alejandro Avellaneda noticed two airborne shapes only after reviewing a photograph from Villa Tacú. CIAE found paired wing-like appendages and body shapes consistent with flying insects. Their close association suggested possible courtship, which the report presented as probable rather than established behaviour. The agency classified the insect explanation Type B, acknowledging that the fleeting photographic event could not be recreated. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes. The map uses an approximate GeoNames locality centroid, not the observation point.
