Abstract
Ninety percent (865/962) of the billbugs (Sphenophorus spp.) in 145 to ad (Bufo boreas Baird & Girard) fecal pellets were egested alive. Dead billbugs (S. phoeniciensis Chittenden) found intact in toad fecal pel lets have an average weight and caloric content that was 1.4% (0.13/9. 06 mg) and 4.5% (0.225/5.049 kcal) greater, respectively, than that fo und for non-egested billbugs. Toads (B. boreas) derive no calories fro m billbugs (S. phoeniciensis) that pass intact through the digestive t ract.
