Walk through a butterfly house and you'll feel like you're peeking into a world usually only seen on a nature show. Butterflies of various sizes, colors and patterns flit from flower to flower. Others perch gracefully on limbs and stems.
"They're everywhere, they're so huge," squeals Jessica Cohen, 9, of North Patchogue, as she glances around the Island's largest vivarium at the Long Island Aquarium and Exhibition Center in Riverhead. She squeals again as one lands on her shoulder.
"It is so magical," adds mom Jen Cohen, looking over at butterflies that range from an inch or so across to giants with an 8-inch wingspan.
These vivariums are designed to house butterflies and moths in environments that mimic their natural habitats:

Visitors can walk ground-level paths, or stand on the overhead observation bridge for a bird's-eye view of the upper canopy of exotic plants and trees where some butterflies go to rest between feedings.
"I kept asking how to get one to land on me," says Candace Fedele, 23, of Holtsville, who climbed the stairs to the observation level. Perched on one hand is a 3-inch-tall Owl Butterfly, which has a large, round spot and markings on each wing that look like peering owl eyes. "And, I come up here and this giant one . . . just plopped down on me. It's creeping me out, but is sort of cool, too."

MOST UNUSUAL VARIETIES Striped Zebra Swallowtail, Black Swallowtail
This outdoor vivarium that houses all native species is a lot like sitting in someone's flower-filled backyard. Because it has larvae host plants, visitors may also see mating butterflies, eggs, caterpillars and chrysalis.
"You can get so close to them here," says Pat Bridgwood, 56, of Medford, who was accompanied on a recent weekday by granddaughters Kaylee, 5 1/2, and Jamie, 2. "In the yard, they fly away as soon as the girls walk toward them."

MOST UNUSUAL VARIETIES Green-and-black striped Malachites; striped Zebra Longwings; and the swift-flying Spicebush swallowtails, which are difficult to get a good look at in the wild.
Open since 1997, this is Long Island's oldest butterfly house. It hosts native and nonnative North American species. While 20 species call Sweetbriar home, expect to see about 10 species during a visit, says program coordinator Nancy Adornetto.

3 tips for visiting
1. Watch where you step -- butterflies often land on the floor to rest.
3. Wear bright colors (reds, oranges and yellows).
