This beetle is mostly yellow with three very obvious black stripes along its body, and 2 black dots on its pronotum behind the head. My beetle also has whitish stripes next to the black ones. It seems this beetle can also have a brighter orange head, pronotum, body and legs.
The eggs are quite distinctive as they have black tips.
The grub-like larvae are also different in that they carry their ‘poo’ on their back.
There is also a three lined potato beetle which is very closely related but a brighter orange colour, without the white stripes next to the black.
Also similar is the cucumber beetle, which doesn’t have the white stripes next to the black stripe nor the two dots behind the head. All are leaf-eating pests.
Adult size: 7 mm
