Naturalists learn of smallest backyard creatures

It has been said that biodiversity is the key to ensuring the continuance of life on earth. During the Jan 20th lecture on Insect Biodiversity in the Mississippi Valley Field Naturalists (MVFN) Biodiversity series, research scientist Dr. Henri Goulet’s knowledgeable and passionate presentation highlighted an important issue, just how little we actually know about the living organisms in our own backyards. Insects and other arthropods are by far the most diverse of small life forms in Ontario, yet Dr Goulet estimates that we know less than 50% of the species.

Attendee’s, who braved the frigid temperatures of the night, were presented with absolutely dazzling slides of some of the 230 species of insects alone that frequent a few flowering heads of goldenrod. It truly is a jungle out there with insect species representation from herbivores, parasites, predators, and nectar & pollen feeders. To put this diversity in perspective, during this year’s Carleton Place Christmas bird count, 45 species of birds were recorded in a 15-mile diameter circle around the town of Carleton Place.

Biodiversity is considered a fundamental requirement for adaptation, survival and continued evolution of species and Dr Goulet’s microscopic insect world was alive with insects adapt at cryptic hiding, mimicking patterns that would make them less susceptible to or better at predation. As each of us gains a better understanding of biodiversity, we will be able to make better decisions about our environment, starting in our own backyards. Such as taking Dr Goulet’s lead, who, after noting their genocidal effects, declared his own backyard drug (pesticide) free. Dr Goulet was kind enough to share with the MVFN some of the presentation’s slides (such as a preying mantis mimicking a wasp), which will soon be posted on

Mark your calendars for MVFN’s 5th Biodiversity lecture (Communicating the Issues of Biodiversity), that will be given by Andrea Howard of the Eastern Ontario Museum of Biodiversity on Thur. Feb. 17th at the Almonte United Church, 106 Elgin St. at 7:30 pm. If you are not yet a member of the MVFN, this may be a good time to join.
