When young trees, many white pines are predated by the white pine weevil, a small insect that lays its eggs in the topmost branch of the tallest juvenile white pines growing in open sunlight. This damages the trees’ leading shoots and causes the lateral branches below to grow into crooked, split trunks. Abundant crooks and double trunks on are a clear indicator that the white pine weevil was hard at work.
