« Ontario Field Naturalist's Toolchest
bug-like creatures like spiders
and centipedes form the most diverse group of animals. With
so many species it is impossible to find a guide to identify them all.
Butterflies and odonates are well known and have many
excellent field guides to choose from. Other groups have only
a few field guides to choose from if any. The generalized
insect field guides won't get you down to exact species often but it
may get you as down to insect family or genus and will always get you
insect order. With a close-up focusing pair of binoculars,
butterflies or odonates can give you much the same thrill as birding
because you can easily see dozens of species on a single outing.
Illustration based. Introduction to bugs. This book features 125 of the coolest bug species. That is bugs that are big, colorful, hard to miss or weird. It is an excellent introduction to bugs and will help you identify many of the most common insects. The descriptions of each species are quite interesting. The best way to use this book is to go on trips to find specific bugs listed in the guide instead of using it to identify what you find.
Insects of Algonquin Provincial Park Pub GB
Photograph based. Very cheap book. 8*11 size makes it difficult to take into field. If you live close to Algonquin Park then it should be possible to see anything in this guide. A good feature of the book is a key to the orders of winged insects found in Algonquin Park
Insects of the Great Lakes Region GB
Illustration based, black and white. Local common insects. Good for insect life histories. Region covers Ontario but also the states surrounding the great lakes.
Insects of the North Woods Pub GB
Photograph based. Semi-local common insects. Useful for those living on the western edges of Ontario as a field guide, perhaps more useful than a North American guide. Interesting nature notes. Good introduction as well.
North American Field Guides
A North American field guide can fill in the gap in what is not covered by our regional guides or guides for specific groups of bugs. There are definitely lots of cool looking bugs outside the groups of bugs most commonly studied. These North American field guides are in my opinion all have different strengths and weaknesses that make it difficult to choose a winner.
Illustration based, black and white with color plates. Oldest and least colourful but the best at showing the key identifying features of insects. Uses mostly black and white paintings (~1300) with some color paintings (142). Will allow you to identify most insects to family level.
Kaufman Field Guide to Insects of North America GB
Photograph based, digitally altered. Coverage for each insect species is very brief but this guide covers more species than the others.
National Wildlife Federation Field Guide to Insects and Spiders & Related Species of North America GB
Photograph based. The classification level of the insect (class, order, family, genus etc) is well presented.
Garden Insects of North America: The Ultimate Guide to Backyard Bugs (Princeton Field Guides) Am
Photograph based. Geared towards people interested in removing pest insects from their gardens or just learning about what insects are in their gardens.
North American Reference Guides
Reference, technical. The most comprehensive insects keys are in this book. Mostly for insect researchers.

Reference, Eastern North America, photograph based. This book by the same author as Insects of Algonquin Provincial Park but is far more detailed. Excellent and usable illustrated key at end of book.

These next three websites are the most useful:
BugGuide.Net If you can't identify an insect try this website. Post your picture and somebody might be able to identify it. The website has perhaps more insect species photographed than any other resource. Plus it has hundreds if not thousands of links of to other resources and books.
Ontario Insects Ontario's insect portal. Includes upcoming field trips and insects counts, publications (many downloadable), and a host of other interesting stuff.
Canadian Journal of Arthropod Identification New field guides for various groups of insects coming out periodically. Definite scientific angle but the photographic keys make the field guides quite accessible for amateur naturalists.
