Brief description of what you observed
Posado sobre un bote de basura, cerca de encinos.
Largo: 10 mm
Ancho: 9-10 mm
Eggs. As many as 20 are laid, at the angles shown.
Have been removing as many as possible as beetles when eating leaves also eat Monarch and Queen eggs.
Bad common name - it certainly likes other Milkweed species.
