Once a dead mouse is found, the male and female beetles hollow out a small chamber in the soil by the mouse. Then the mother beetle lays her eggs in the chamber. Both the mother and father guard their nest.

“W E enjoyed Behold and See 4 so much last year that we decided to review the health & nutrition unit again. The ‘Nice-cream’ snack has been a healthy yummy treat

for our family, especially since our Texas weather is still hot! We love CHC!”
