were also seen resting on the exterior walls of the latrines under the 

 outside lights and around the entrance. The number of flies collected 

 decreased dramatically with increased wind velocity. At Fawcett Boy 

 Scout Camp, sand flies were also taken in resting collections in a 

 lighted, open-air latrine (Fig. 2-8). 



An extensive search for natural diurnal and nocturnal resting 

 sites of Lu_. diabol ica in rock crevices, under bark of trees, in 

 animal nests and burrows, in leaf litter, and other potential hiding 

 places was fruitless at all case sites. 



Female Uj. diabol ica were often taken in biting collections during 

 the evening hours at Garner State Park as they came in search of a 

 blood meal. Routine biting collections netted from one to about 

 twenty female sand flies per hour. One biting collection, however, 

 was worthy of special note: The night of 9 June, 1982, was hot and 

 humid (27°C and 80-90% RH) and air movement was about nil. The author 

 and his son had returned to the field laboratory (a screen tent) about 

 2330 hrs after searching the latrines for resting sand flies. They 

 sat under an incandescent light at a table inside the tent and began 

 to count and feed the evening's catch. Shortly the author's son began 

 to complain of being bitten by sand flies, and five were collected 

 that were biting him on the legs. j-u. diabol ica females flew 

 unobstructed through the screen sides of the tent in waves of ten or 

 twenty to feed, biting the occupants on the face, neck, hands, ankles 

 and other exposed skin. These foraging sorties were of about five 

 minutes' duration, with a brief respite interval between. They 

 continued for several hours and about 150 female Lu. diabol ica were 

 collected before 0100 hrs, when the author finally retired for the
