night. Even with the light turned out, the flies continued their 

 attack, but in lesser numbers. 



On several occasions, foraging females were seen flying through 

 the standard mesh screen of the permanent camping shelter (field 

 laboratory) to attack the author and his eight-year-old son. They 

 seemed to exhibit a preference for the son, biting him even after the 

 lights had been turned off. Although most of this biting activity 

 occurred at night, one female Lu_. diabol ica bit him at about 1400 

 hours in the heat of the day and in full sunlight (temperature about 

 38°C, RH about 60%, air calm). 



Lu. diabolica were collected in unbaited CDC light traps at Garner 

 State Park, Rio Frio, and Seminole Canyon State Park in June 1982. 

 They were also collected in C0 2 baited CDC light traps (with light on) 

 and in a New Jersey light trap at the site in D' Ham's in September, 

 1983. Unbaited CDC light traps (light only) were unsuccessful at the 

 D' Ham's site. 



One female Lu. diabol ica was collected in a Shannon trap at Garner 

 State Park. The trap was set up near the camping shelter about an 

 hour before dark (1800 hrs), but was only operational for about three 

 hours due to inclement weather. Other attempts to attract sand flies 

 to a Shannon trap at D'Hanis and Devine failed. 



Disney traps set out near rodent burrows at Garner State Park 

 failed to collect sand flies as did oil traps set out in similar 

 places at D'Hanis and Devine. 



Lutzomyia anthophora . Lutzomyia anthophora were taken with Lu . 

 diabol ica in resting collections in latrines at Garner State Park and 

 Fawcett Boy Scout Camp. They were also taken from armadillo ( Dasypus 

 novemcinctus ) burrows at the former site.
