Hi Mary, I'm not sure precisely what you are asking. Do you need kid-level information on insects? Or how to determine sources for a bibliography for information in general? Or a question about self-publishing?
If about whether a bibliography is needed for self-publishing, I am no expert on that but it seems to me you could do what you want and "buyer beware" regarding the quality of the information.
I am an expert on insects, though
(entomologist by education and experience) You might start off with
4-H, which I suspect they have in Canada as it has an international office. I found entomology
resources through their webpage. When I was associated with the ent department at Mississippi State Univ.,
Bug Camp was one of the most successful outreach events of the year. 4-H was involved with MSU bug camp, although I don't see them mentioned on the Bug Camp site. For that matter, most of the "land grant" universities in the US (and more specifically usually those with "State University" in their name) have a cooperative extension service that does youth outreach, and in some ag states the ent extension is very active (Iowa State, Ohio State, Michigan State, Oregon State, and Colorado State all come to mind immediately). In Canada, I think University of Guelph might be active in agricultural outreach. You could also look to
Scouting BSA (formerly Boy Scouts) or
Girl Scouts to see what nature education they do.
