Colorado potato beetle

Leptinotarsa decemlineata

The adults measure about 3/8 inch long and are yellowish-orange with multiple black stripes down the back with five per elytron (Wilkerson et al. 2005). They are robust and oval in shape when viewed from above. The head has a triangular black spot and the thorax has irregular dark markings. In Leptinotarsa decemlineata, the pale yellow elytra are outlined in black, with each elytron having five vittae (broad longitudinal stripes). Vitta 1 is shorter than other four and adjacent to the sutural margin. Vittae 2 through 5 extend more than half the length of the elytron and are very distinct. Elytron punctation is coarse in irregular rows. The underside of the beetle and the legs are mostly dark.
