Common signs of this little plant sucker are broken or wilting tops of milkweed plants, small holes in stems near top of plant that may be oozing white milkweed sap.
The least harmful method of removing these is to periodically check plants and manually squish weevil between your fingers or drop in to a cup with water.
Too many of these weevils can ruin a healthy stand of swamp milkweed. usually hiding in new leaf buds at the top of the plant they will drop to the ground when threatened. being the color of soil it is practically impossible to locate them
Many times found in pods feeding on seeds in the fall, or in stems and roots of dormant swamp milkweed plants
