caterpillar enemy?

Of the five varieties of passion flowers in the yard, the Gulf Fritillaries seem to show the ‘Lady Margaret’ and the Passiflora caerulea the most attention. However, both of these plants are crawling with what appears to be wasps or hornets. The GFs and Zebras are laying eggs all day on these two plants especially, yet there appears to be little caterpillar activity. This has gone on for a month or two now and I would rather let Mother Nature take care of the balance. Any advice?

My others passion flowers, ‘Alba’, ‘Corky-stemmed’, ‘Lutea’, and 'Lavender Lady' are getting some butterfly passers-by and caterpillars, but not as prevalent as the aforementioned.

Cowabunga! I am not the judge of these things. Great shots though. If you want the cats the wasps must go.

There's nothing wrong with helping "mother nature" out a little, IMO. Sometimes we don't have time to intervene or get involved, and sometimes there's nothing you can do. I would not like the wasps around so much, but then I am not sure how to get rid of them either. You could put a sleeve around the vine. I know people who have used paint strainers from Home Depot (I still need to get myself one!) They are apparently made of mesh and tie on one end, so you can put part of the vine with the cats inside then close it off.

I usually bring my cats indoors when they get near pupating, but I don't with the GF's. The vine is too hard to bring inside to feed them, unless you have a lot of vine. (mine is always small) They do fall prey quite often to spiders here. I try to knock the spiders off the vines when I see them.

Being a lover of passiflora, I say wasps deserve to eat, too. I keep a couple of large passiflora in the ground for the cats. The rest of my vines are for flowers and leaves. I do have a huge population of various wasps--not my favorite bug. I bet they are attracted by the buffet!
