Adult butterflies live for only a few weeks, but you can still fill your yard with these Liberaces of the insect world if you take the advice of Tom Terrific. Terrific, a St. Louis resident and the author of Ten Commandments of Butterfly Gardening, discusses his comprehensive guide to attracting butterflies at -- where else? -- the Sophia M. Sachs Butterfly House (15193 Olive Boulevard in Faust Park, 1 p.m.). Before butterflies can fly, they've got to be eggs, caterpillars and chrysalises. Making sure that conditions are just right for each stage is an art and a science. For instance, caterpillars are picky eaters, and they require certain host plants. Butterflies are attracted to highly colorful, nectar-bearing flowers only. Also, sunlight is important, because butterflies are cold-blooded animals that actually need heat to fly. As is true with many gardening projects, writes Terrific, you'll probably have to deal with marauding rabbits, too.
The $20 fee for Terrific's presentation includes a signed copy of his book (call 636-530-0076 to pre-register, and visit www.butterflygardening.org). -- Byron Kerman
The serious disc-golfers will brave icy conditions to play their sport on courses in Creve Coeur Lake Park and other area spots, but summer is when they really hit the links -- or the baskets, in this case. For the uninitiated, disc golf is just golf played with a Frisbee, on an eighteen-hole course with steel baskets instead of tin cups. It's a load of fun -- so much so that you may become an addict with specialized techniques for throwing the "hyzer" (a throw that breaks to the left) and the "anhyzer" (a trickier "slice" throw), and you may even possess a bag of different discs for use with different "shots." The Drive to Thrive Disc Golf Tournament, sponsored by the O'Fallon Jaycees and Gateway Disc Sports, includes a playing lesson, barbecue lunch, raffles, prizes and two rounds of play at Wentzville's Quail Ridge Park (the Southwest corner of I-70 at I-64 on Callahan Road). The 9 a.m. contest benefits the Wonderland Camp for the disabled ($15-$20, 314-330-2484). -- Byron Kerman
My Market Has Fleas
Double your bargains
Jefferson Barracks Park has turned each parking space in its capacious lot into a stall for a junk vendor. The one-day Parking-Lot Flea Market (9 a.m.-4 p.m., 533 Grant Road, 314-544-5714) means hundreds of booths and thousands of bargains, from Cardinals caps to costume jewelry to antique tools to those water-balloon yo-yos the kids are into these days. A bit farther afield, the Lewis and Clark River Market is both a farmers' and flea market, with fresh tomatoes, knickknacks, live entertainment and food and drink sales (8 p.m.-1 a.m. each Saturday through August, 200 Piasa St. at Rte. 100 in Alton, 618-463-1016). Admission to both markets is free. -- Byron Kerman
