Anthonomus pomorum explained

Anthonomus pomorum or the apple blossom weevil is a univoltine herbivore of apple trees, Malus domestica.^[1]

Life history

Adults generally overwinter in leaf litter of forests or hedgerows. In the spring, they emigrate to orchards and colonize apple trees.^{[2] [3]} They may find their host trees using pheromones or plant-derived chemical cues.^[4]

Spiders can be effective predators of A. pomorum.^[5]
