Placosternus difficilis

Placosternus difficilis, commonly known as the mesquite borer, is a wood-boring longhorn beetle[1][2] which resembles a black and yellow wasp.[3] Larvae of mesquite borers are deposited in, among others, mesquite trees, although it has been recorded from a range of hosts and is considered polyphagous.[4] It has been seen to be attracted to mesquite trees when there is freshly cut or broken limbs and logs. Adults use nectar and pollen as a food source.[5][3][6][2]
