This small collection is situated in the Montreal Botanical Gardens. The Botanical Gardens themselves are fantastic and apparently the second largest in the world (not sure where the largest are?). You can purchase a combined ticket for the Gardens, Insectarium, Montreal Biodome and the Planetarium (both at the adjacent Olympic Park) for around $50 CAN. Pretty good value. The Insectarium itself occupies a small purpose built building on the Gardens grounds and is part live collection, part museum with lots of mounted specimens. The live collection covers arachnids, myriapods and crustacea, as well as insects, with an emphasis on stick insects and phasmids, contained in naturalistic enclosures over two floors (actually some of the largest enclosures for invertebrates I have ever seen in some cases......I have seen birds in smaller enclosures than some of the stick insect enclosures!!). It is far from huge and can be viewed in detail in an hour, so lots of time to spend in the rest of the Gardens!!
