Is it harmful that my rabbit eats bugs?

My rabbit is now eating bugs such as crickets and those things. She hasn’t shown any signs of health problems while she ate them, but I’m not sure if they’re healthy at all for her. The crickets are just in our normal backyard, and every time she runs around the yard, she eats bugs – especially crickets. She apparently wants to eat with her normal feeding. They do live in my backyard and she has eaten some of them inside her burrow to "defend" her burrow. Would bugs harm her in any way?
