Which Milkweed?

[petereeles]

Hi all,

Last year I visited the Dominican Republic and managed to photograph a Monarch ovipositing. I'd really like to know what foodplant is being used - given the location, I expect Asclepias nivea (Caribbean Milkweed), but since I live in the UK, I'm not overly-familiar with different Milkweed species! Photos can be seen at:

Thanks in advance for any help.

Cheers,

- Pete

Your pictures appear to be that of the Carribean milkweed. That would account for the reason that the Monarchs were using it to lay on.
