Interesting blurb. This would be most distressing for a lep lover. May
I suggest one option for 'controlling' the wasps. A freind was sent a
preying mantis last summer and we discovered that they will quite
happily feed on yellow jackets. The mantis was very effiecient! But as
they would most cetianly eat your butterflies too, may I given an
additional (if unorthidox) tip. We performed our 'experiment' on the
patio during dinner time. The yellow jackets would come when ever there
was bbq meat. So we opted to put aside a small peace offering with our
mantis perched atop. Wonderful trap! I'd highly recommend it as a
biological control method. Hope this suggestion helps.

>2 - Confirming last summers suspicions that the more common black &

>surprised to observe one take a much larger, black & blue colored
>swallowtail day before yesterday. After engaging the swallowtail on
>a bloom, the two tumbled down through the branches and leaves of the
>butterfly bush to the ground. With its tail curled over the top,

>approximately 1 third to 1 half of of the thorax from the underside,
>processed it into a pulp ball, and flew it away from the site,
>leaving the wings intact with the remainder of the body. Unlike with
>the yellow-orange hornets, I was able to make this observation at
>approximately two feet.
>3 - Yesterday I checked the spot where the above butterfly remains

>was surprising was that a close observation of the ground beneath the
>butterfly bush today, revealed no less than four, and possibly five,
>piles of yellow swallowtail butterfly wings, or wings with bodies
>less heads and portions of thorax, as described above. It also
>revealed remains of one or two additional black & blue swallowtails.
>One of the yellow swallowtails still had a few of its legs and they
>were still moving.
>4 - In addition to seeing both yellow-orange, and black & cream,
>hornets searching over the bush today, I also observed a
>yellow-jacket following the same pattern of skimming over the blossoms
>and bumping into any occupant there-on. Having observed a
>yellow-jacket take a candlefly a number of years ago, I now fully
>expect to observe one take a small butterfly.
