Description:
<jats:p>
Capture-recapture studies revealed that the checkerspot butterfly

is extraordinarily sedentary. Since no physical barriers prevent interchange between various portions of the study colony, it is concluded that intrinsic factors play the major role in limiting movement. The few available data on dispersal are discussed.
