An uninvited guest has ruined Kurt Busch's wedding plans.

No, not Jeff Gordon.

Apparently, the temporary pier Busch wanted to build on the Chesapeake Bay for the matrimonial festivities would have infringed on the habitat of the tiger beetle -- during mating season, no less. The beetle in question is designated as a "threatened" species under the Endangered Species Act.

And so thanks to the U.S. Fish and Wildlife Service (and some apparently very horny beetles), Busch and fiance Eva Bryan will have to go ahead with their wedding next weekend at an alternate site.
