Fig. 5. Spatial and temporal distribution of Pyrgus oileus (dots) and 
Pyrgus philetas (circles) in Texas. Half dots indicate known points of 
sympatry. The more interior and northern records of P. oileus probably 
represent transient populations (see text). Temporal distribution is crudely 
expressed in a month by month tally of all dated specimens examined.
