' FLIGHT BEHAVIOR
- Sand flies are weak fliers, travel in short hops rather than in sustained flight
- Flight range is a function of habitat and host availability
        -  Forest, 50-200 meters
        -  Savana, 200 m 2.2 km
- In forests, vertical dispersal between canopy and forest floor is common
- Fly only at night unless disturbed in their daytime resting site
- Winds speeds in excess of 1.5 m/sec inhibit flight; flight ceases altogether in light winds of 4-5 m/s
- Most fly horizontally near ground level
          -   Less air movement
          -   More animals
