butterflies and dragonflies steal the limelight, the vast majority of
species are either beetles, flies, true bugs, or Hymenoptera (made of
ants, bees and wasps). Too much diversity in fact for most
naturalists. Too much diversity also results in few
field guides. Those that are comprehensive can be rather
technical. So with the majority of orders that follow I mark
a star resources that experienced amateur naturalists can utilize
without too much difficulty.
Hymenoptera: Bees, Ants, Wasps
Another diverse order of bugs with few relatively accessible resources.

This long awaited field guide is coming out May 2019. This breakthough guide will make these striking flies much more accessible to naturalists.
Hover Flies/Flower Flies
A field guide is in production, but these resouces below should help. The key to genus is a place to start - but you may not have enough info in your photo. Once you have the genus you can check out the Field Guide to the Syrphidae of Ontario and the EOF entries. Bugguide.net may also help especially if the genus key doesn't work for you.
*Field Guide to the Syrphidae of Ontario. Photograph based. While studying flower flies aka hover flies is popular in Europe this website is a first for Ontario. You may it distasteful the fact the insects are impaled for the purpose of the website.

Incredibly there are field guides to both mosquitoes and black flies complete with range maps and coverage of all the species in North America north of Mexico. These books are not only useful for keen field observers (with patience for scientific jargon) but also researchers and for people involved in mosquito or black fly control programs.
The Black Flies (Simuliidae) of North America GB Reference.
The black fly book is more detailed and probably includes hard to read research reports. It includes species descriptions and in fact contains nearly all published information on black flies. The mosquito book is mostly a detailed key.

The appeal of orthoptera is that many have songs and mating displays. A recommended piece of gear for orthoptera are breathable ziplock bags. Cheap and doesn't fry or suffocate the bugs you are trying to identify. Ziplock breathable bags
*Field Guide To Grasshoppers, Katydids, And Crickets Of The United States Am Ch
Photograph based, illustrated key. My top recommendation. Beautifully illustrated color plates. Good illustrated key. Downsides are it covers only 1/3 of the species and splits pictures from species accounts. Makes a great beginner's guide. A companion website, Singing Insects Of North America, has useful recordings and covers all the species of crickets and katydids of North America. The website also covers some cicadas (in the order true bugs).

Mayflies, caddisflies, stoneflies and other aquatic insect orders are mostly of interest to people who do fly-fishing. These aquatic insects are great bioindicators and is a chance for "fly-fishermen" to contribute to science if they tracks these insects. Flyfishing Entomology is the main site on the internet about this topic. From that website is their recommended books and entomology bookshelf.
