This Monarch butterfly is a boy! You can tell because there is a small black dot on his hindwing (lower wing). Look for it on the narrow vein close to the butterfly’s abdomen (back end of his body). Who ever thought sexing butterflies could be so easy?
Here is a shot of the underside of the hindwing. This Monarch is enjoying nectar from wing stem sunflowers. Find some tasty flowers and enjoy butterfly watching while the weather is still warm and wonderful.
