These little weevils have been released in MT as a form of biological control to fight against Dalmatian Toadflax. The adults (pictured here) emerge from the plant stems in the early spring with two things on their minds …feeding and mating. Feeding from the adult weevils impacts the shoots and the development of flowers and seeds. Females will lay up to 45 eggs that hatch within a week or two. The larvae bore into the stems of the plant, impacting the amount of water and nutrient uptake by the plant. Click here for more info.
