Globe Trotting Insects!

I unknowingly flushed this Wandering Glider. I waited patiently for it to return and It landed not far from where it was first spotted! The Wandering Glider is the only species of dragonfly that can be found on every continent other than Antarctica. They have very broad hindwings which make them strong flyers and allows them to migrate further than any other insect, including Monarchs! They have even been found perching on ships far at sea.

I finally found a Painted Lady in September when it landed right at my feet with its wings spread! The Painted Lady butterfly is found on every continent except Antarctica, making it the world's most widespread butterfly species! The caterpillars feed on over 300 host plant species which helps them to survive in so many different environments. The population in North American tends to stay in North America. Another population moves between sub-Saharan Africa and the Arctic Circle via Western Europe, spanning roughly 9,000 miles. Unlike fall Monarchs which travel the entire distance to Mexico, each Painted Lady Butterfly only flies a portion of the trip. It takes several generations to complete each migration.

Some "fresh from the chrysalis" Eastern Commas have been basking in the sun recently. This species does not migrate, but will overwinter as an adult under pieces of bark or other places that protect them from the winter elements. They are one of the first species to emerge in the spring. I used to regularly see them in the month of March when I worked in the sugar bush. Maple Sap dripping from the trees is a good source of food when flowers aren't in bloom.

The silvery-white comma shape on the underwing gives the Eastern Comma their name.

I usually see Eastern Commas sunning on tree bark so it was nice to see one drinking nectar from some Asters.

A Fiery Skipper also enjoyed the asters and the sunshine!

I continue to see at least one Monarch daily as they migrate south. They have been enjoying the native Boneset blooms growing in our backyard.

I was happy to see my second Common Buckeye of the year. On the cooler days, butterflies tend to stay down low and find places where they can soak up the sun.

It was a treat to find a Common Buckeye that wasn't resting on the ground!

I continue to find the "uncommon" Common Checkered Skippers!

Strong winds on September 18th kept this Spiderman kite airborne all day long! It may have been stuck in a tree as I didn't see a person at the "land end" of the string on either of my walks into Canatara that day.

 A September 17th visit to Pinery PP.

A Northern Parula was displaying his beautiful sunrise throat as he searched for the insects we were trying to photograph!

Red-eyed Vireo caught a caterpillar. In the second photo it appeared satiated by its snack!

Black and White Warbler searching for insects under the bark. They have an extra long hind claw and heavier legs than other wood-warblers, which makes it easier for them to hold onto and move around on bark.

We have been visiting the Pinery, taking advantage of the good weather to search for insects before they go into their winter hibernation. Some of our recent finds follow:

Hemlock Looper Moth

Skiff Moth caterpillar. This time it was on the underside of the leaf!

Variable Oakleaf Caterpillar

Boreal Pine Looper Moth: Many moths and other insects were found on the exterior walls of the comfort stations. Lights on the buildings attract these night time flyers, who then sleep through the day.

Fringed Dart: A new species for us that is only found in the Grand Bend area!

Winter Firefly

3 Turkey Vultures, just before they took advantage of the winds and soared over Lake Huron.

 Canatara, Naturally!

This was possibly my best ever look at a Philadelphia Vireo! They breed in the boreal forest and are most often seen during Spring and Fall Migration in southern Ontario. They are smaller and less aggressive than Red-eyed Vireos and tend to forage for food in the upper canopy of trees to avoid competition with the larger vireo. Favourite foods include caterpillars, spiders, beetles, wasps, ants, moths and flies. Philadelphia and Red-eyed Vireos sing very similar songs. Where these two species overlap on the nesting grounds, the Philadelphia Vireo may sing perfect imitations of Red-eyed song. Scientists speculate that these imitations might help the smaller Philadelphia to avoid aggression by the larger, heavier Red-eyed Vireo.

I was lucky to find this Bay-breasted Warbler still wearing fairly bright spring colours. Typically in the fall, they become a greenish colour, making identification difficult. Their population numbers vary from year to year and are likely to increase quickly during population explosions of the Spruce Budworm.

On the cooler mornings, if you look in "just the right places", it is possible to find Common Green Darner Dragonflies and other species drying off their wings and waiting for the sun to warm them!

Great Blue Heron

House Wren - a very noisy chatterbox!

This Asteroid Moth Caterpillar was so well camouflaged that I had to take a couple of looks to determine I was actually looking at a caterpillar and not a leaf!

Young Male Rose-breasted Grosbeak that likely was raised in Canatara Park.

I followed a "murder" of American Crows as they cawed incessantly. Often it means they have uncovered the hiding spot of a Hawk, Owl or Eagle, but this time I think they "just wanted to make noise!!"

The noisy crows led me down a path where I noticed this White Underwing Moth. These moths which are members of the 'Family Noctuidae' have evolved a trick for dealing with bats. They can actually hear the bats as they are attuned to the exact frequencies of sound that bats use for echo-location. When the moths are flying about and hear a hunting bat, they will fly downward in an erratic manner, seeking a place to hide until the bat departs!

Ring-billed Gull Play time! A Ring-billed Gull spent several minutes playing with the short stick. It kept dropping it and picking it up before the waves could carry it away!

New Butterfly&Dragonfly Species!

A new butterfly species for us! Native to Europe, North America and Asia, the European Common Blue was first recorded in 2005 near Mirabel Airport in Quebec. It has since been slowly spreading east, south, and westward with the earliest record in Ontario in 2012. There are now many records in the Greater Toronto area.

Underwing of the European Common Blue which we found near Hamilton.

The Great Spreadwing is listed as Critically Imperilled on iNaturalist. The only known Canadian population was in Essex County, but none have been reported in that area since 2024.  A population was found this summer in Lambton County!

2 pairs of Great Spreadwings were recorded mating at the Lambton County site. Hopefully they will be able to establish a population!

We spent a relaxing morning walking the trails at Henderson Conservation Area near Petrolia.

A well camouflaged Great Blue Heron is sitting in the branches of a fallen tree, providing a great vantage point for hunting!

The reservoir behind the back weir at the Conservation Area had just the right amount of water for some migrating shore birds!

Spotted Sandpiper - running along the rocks at the edge of the water.

Lesser Yellowlegs - We saw about 28 individuals. They were scouring the mud for invertebrates. 

Osprey hunting for fish

Turtle nest cover to protect the eggs from skunks, raccoons and other predators.

One of our goals at the C.A was to find slug moth caterpillars. We found 3 species. Yellow-shouldered Slug Moth caterpillar

Red-crossed Button Slug Moth caterpillar

Purple-crested Slug Moth - so well camouflaged!!

Spotted Apatelodes Moth

Small reservoirs were created over fifty years ago at Henderson C.A. to help slow the flow of water as it continued down stream. Drop-tube inlets were installed so water would have an exit without flooding surrounding land. One of the drop-tube inlets (shown on the right), sprung a leak back in the spring. It has since been plugged and alternate flood control methods have been installed.

However, the lack of water at the shallow end of the small pond has allowed plants to grow where they normally wouldn't be found. Hopefully the pond will fill up naturally with rain water in the coming months to improve aquatic habitat for the species that depend upon it.

Monarchs are continuing to pass through the region on their way to Mexico!
