Diurnal activity and territorial behavior of the tiger beetle, Pseudoxycheila tarsalis Bates (Carabidae: Cicindelinae), were studied in San Vito, Costa Rica, by marking the beetles, observing their behavior and distribution, and timing their activities. We tested hypotheses that: 1) beetles were randomly distributed in the study area, 2) male and female beetles moved equally throughout the study area in one day, and 3) males and females moved the same distance over successive days. Beetle activity increased with increasing temperature and decreased with cool, rainy, or cloudy conditions
