observation consistent with Parman's statement (1919) that the sand 

 fly was found in Uvalde in the more elevated parts of the city. 

 Perhaps this is a clue as to where other resting sites are to be 

 found. 



Parman (1919) reported that the earliest authentic record of 

 appearance of Lu. diabol ica in Uvalde was 3 September and the latest 

 was 24 November. Lindquist (1936) reported collections between 3 May 

 and 16 November from Uvalde. Although no collecting was done in 

 Uvalde during this study, Lu_. diabol ica were taken in resting and 

 biting collections at nearby Garner State Park (50 km north of Uvalde) 

 as early as 4 June and in light trap collections at the D'Hanis site 

 (50 km east of Uvalde) as early as 5 May and as late as 4 Oecember. 

 Specimens of this species were taken at Garner State Park in human 

 biting collections by Young (1972) as early as May 17. Adults are 

 probably present in these locations throughout the frost free season, 

 with populations increasing over the summer months and reaching a peak 

 in the fall when they reach a nuisance level and are noticed by the 

 public. Parman (1919) apparently based appearance records on biting 

 activity. If so, this is consistent with the idea of a gradually 

 expanding population over the summer months. Surveys throughout the 

 year in and around Uvalde will be essential to confirm this idea. 



Parman (1919) believed that Lik diabol ica never venture out of 

 hiding until well after sunset and never attack earlier than one hour 

 after sunset. Wilkerson (pers. comm., 1984) collected a female Lu . 

 diabolica biting him at 1400 hrs in full sunlight in mid July at 

 Canyon Lake, Comal County, Texas. During the 1982 research trip one 

 female was collected while biting the author's son at 1400 hrs in full 

 sunlight (temperature 38°C, RH approximately 60%). These may be
