Sand Fly Diversity and Distribution in Grand-Est, France, Summer 2025

Grand-Est, France, is the focus of a field study on sand flies, vectors of Leishmania and phleboviruses. The dataset includes results from 146 samples collected at 25 localities in July-August 2025, detecting 36 specimens across 12 sites. Authored by Francis Schaffner, the data was last updated in May 2026.

Use Cases

• Modeling the northern range limits of sand fly species based on presence/absence data from field traps.
• Assessing vector-borne disease risk in a temperate region based on species identification and locality data.
• Comparing sand fly habitat preferences based on site categories like barns and dry stone walls mentioned in the description.

Strengths

• Data is recent, collected during a focused field campaign in summer 2025.
• Includes a technical report providing context and methodology for the 146 samples collected.
• Extends a previous 2023 study, providing a more complete overview for the region.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (4.8 MB), representing a localized survey rather than a large-scale monitoring effort.
