On the mornings of 5 and 6 March 1977, tracks and feeding excava- 
tions of the Nine-banded armadillo, Dasypus novemcinctus , were found in 
the area containing the highest density of Andrena burrows. The armadillo 
excavations extended to the depth of larval bee cells and fragments of 
opened cells were present. It is doubtful that bee larvae were being sought 
by armadillos; but if encountered larvae would likely be consumed, and 
nests were destroyed by the digging.
