On May 11, 2008, a witness in Blois, France (Loir-et-Cher department) reported discovering unusual shapes in photographs after reviewing them at a later time. Critically, the witness did not observe anything unusual during the actual moment of photography—the anomalies were only noticed during post-review of the images. The photographic evidence showed blurred forms against an otherwise sharp background, a classic signature of objects passing very close to the camera lens at high speed during exposure.
GEIPAN investigators examined the photographic evidence and witness testimony thoroughly. The case was notable for being a 'méprises à posteriori' (post-discovery misidentification), where the witness only became aware of the phenomenon after the fact. The official investigation concluded that the anomalies displayed all characteristic features of insects—specifically described as a couple (pair) of insects—that passed extremely rapidly and in very close proximity to the camera lens during the exposure. This proximity and velocity created motion blur on the insects while the rest of the scene remained in sharp focus.
The French space agency CNES, through its GEIPAN department (Groupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non Identifiés), classified this case as 'B'—indicating a likely identified phenomenon with strong evidence for a conventional explanation. The case serves as a textbook example of photographic artifacts caused by common environmental factors that can appear anomalous when reviewed out of context.
02 Timeline of Events
2008-05-11
Photographic Capture
Witness takes photographs in Blois area. No unusual observations noted at time of photography.
Shortly after 2008-05-11
Anomaly Discovery
During review of photographs, witness discovers blurred, unusual shapes visible in images against otherwise sharp background.
After discovery
Report to GEIPAN
Witness reports photographic anomalies to GEIPAN (CNES) for official investigation and analysis.
During investigation
Photographic Analysis
GEIPAN investigators examine image characteristics: selective blur on anomalous forms, sharp background, paired shapes, consistent with objects very close to lens.
Investigation conclusion
Classification B Assigned
GEIPAN concludes case represents post-discovery misidentification of insect pair passing rapidly near camera lens. Case classified as 'B' - likely identified with high confidence.

04 Analyst Notes -- AI Processed
This case demonstrates excellent investigative methodology by GEIPAN in distinguishing between genuine anomalous phenomena and photographic artifacts. The 'B' classification in the French system indicates high confidence in the conventional explanation, falling just short of absolute certainty (which would merit an 'A' classification). Several factors support the insect hypothesis: (1) the selective blur pattern affecting only the anomalous forms while background remains sharp—consistent with differential motion during exposure; (2) the witness's lack of direct observation during photography, which is typical when small, fast-moving objects pass through the frame unnoticed; (3) the description of paired forms, consistent with insects traveling together; and (4) the May timeframe in France, coinciding with high insect activity.
The credibility assessment is straightforward: the witness appears genuine in reporting anomalies discovered on review, and there's no indication of hoaxing or fabrication. However, the witness's lack of photographic expertise likely contributed to misinterpreting a common artifact. GEIPAN's systematic approach—examining the photographic properties, timing, and environmental context—demonstrates why official investigation yields more reliable conclusions than untrained observation. This case also highlights the importance of understanding camera mechanics and exposure principles when evaluating photographic UFO evidence.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Digital Artifact or Lens Contamination
Alternative conventional explanations could include digital sensor artifacts, lens flare, or contamination on the lens surface (smudges, water droplets). However, the description of 'paired forms' and the specific blur characteristics make the insect explanation more compelling than these alternatives. The lack of direct observation eliminates deliberate hoaxing as a concern.
06 Verdict
ANALYST VERDICT
This case is definitively explained as insects passing near the camera lens during exposure. The confidence level in this assessment is very high (approximately 90-95%). The combination of selective motion blur, lack of direct observation, paired forms, and seasonal timing all converge on a mundane explanation. What makes this case pedagogically significant is not the phenomenon itself, but rather what it teaches about photographic evidence evaluation. It demonstrates that not all 'unidentified' objects in photographs represent genuine aerial anomalies—many are artifacts of the photographic process itself. GEIPAN's classification and detailed explanation serve as a useful reference point for evaluating similar photographic cases. While disappointing from an anomalous phenomena perspective, the case reinforces the importance of rigorous analysis and the value of official investigation in separating genuine mysteries from everyday occurrences.
