Oblique-Lined Tiger Beetle

The Oblique-Lined Tiger Beetle (Cicindela tranquebarica) is a large insect in the Carabidae family of ground beetles. 

The Oblique-Lined Tiger Beetle has a small rounded head, a small thorax (chest), and a long brown-grey abdomen (body). It has yellowish lines on its back, on its wing covers, called elytra. One wing cover is called an elytron. It has wings and can fly. Its antennae are long, black, and ridged. It has a groove on its foreleg with a comb of hairs used for cleaning its antennae. It has bulging eyes. It has six long, thin, hairy legs.

It grows to about 1.2 centimetres (less than 1 inch) long.

It lives in North America. It lives under tree bark, logs, or rocks. It prefers to live near water sources. 

It is diurnal, active during the day. It is carnivorous, eating small insects, especially caterpillars. 

The Oblique-Lined Tiger Beetle is a fast beetle, running up to 9 kilometres per hour (5.5 miles per hour). It runs along the ground in quick spurts. It usually sprints quickly, then stops, and sprints again very quickly. 

The female lays 45-60 eggs, which hatch after 13-54 days into larvae, called grubs. The larvae live underground in tunnel-shaped burrows. Each larva pupates (undergoes metamorphosis) by forming a casing. It emerges after 12-50 days as an adult beetle.
