Dog flea. Light micrograph of an adult female dog flea,Ctenocephalides canis. The helmet-like head (at right) bears a row of combs called ctenidia; these and spines on the body help to anchor the flea in the fur of its host. The eyes are photo- sensitive spots. Below the eyes are blood-sucking mouthparts. The body is flattened laterally so that it is higher than wide,designed for quick movement through the fur. A third pair of legs are elongated and well developed for leaping on and off the host. Only the adult flea is parasitic,feeding on the blood of dogs; the young larvae feed on dead plant or animal matter. Magnification: x19 at 6x7cm size. Magnification: x33 at 4x5 inch size | |
