Lochmaea suturalis, commonly referred to as the heather beetle, is a beetle of the genus Lochmaea native to north-west Europe. It feeds upon heather. They are difficult to spot as they are camouflaged with a brownish colour, and are about 6 millimetres (0.24 in) long. They have a tendency to hide, and they drop into the undergrowth if they are disturbed. They are easier to see when in large numbers on the same plant.
