Abstract : Larvae of C. sanguisuga were collected from the water film between moist fallen leaves and examined under a microscope for signs of feeding. The food of C. sanguisuga larvae was not clearly established. In the present study, no leaf tissue was skeletonized or observed to be ingested by C. sanguisuga larvae, although at least 20 percent of larvae collected from wet leaves were found to have brownish-colored gut contents, which may or may not indicate the ingestion of leaf material. On the other hand, three larvae were each observed to feed on a dead mite and two larvae were observed to feed on a dead nematode. In all cases, a stream of fluid and suspended particles was seen to flow from the mite and nematode into the gut of the larvae.
