The Burtinus bug is a genus of true bugs in the family Alydidae, commonly referred to as flat-headed bugs or sapsuckers. These bugs are primarily found in temperate regions and are known for their distinctive, somewhat flattened appearance. They usually exhibit brown to gray coloration with more subdued markings. The body is somewhat elongated and flattened. Burtinus bugs are sapsuckers, meaning they feed on the sap of plants. Using their piercing-sucking mouthparts, they puncture plant tissues and extract fluids. They typically feed on woody plants, trees, and shrubs.
