Hooray for Pollinators!

 This past week has been National Pollinators Week. While many people think of the honey bee as a main pollinator, and it is a frequent one, it is not a native species. Fortunately there are myriad other pollinators, most of which are native, that will pollinate many different things. After all, if plants weren't pollinated, our choices of things to eat would be greatly reduced!

We are fortunate to have a twelve plot community garden in the municipal park behind our place. It is designed for individual gardeners to grow things for their tables. Sometimes surplus produce is donated to a local food bank.

The garden is coming along nicely, although with the relatively hot dry weather of late, gardeners must water their plot to ensure things continue to grow as planned.

There is lots of diversity of things planted, such as:

Patty Pan

Peppers

Potatoes
Lots of one of my favourites....
Tomatoes

...some of which are already well developed.

There are lots of other things, such as onions, garlic, zucchini, sweet potatoes, beets and others, as well as herbs such as dill and fennel.

Many of these items rely on pollinators to complete their growth and production. Undoubtedly some pollinators would find these plots even in their relative isolation, but in order to increase the chances of suitable pollinators, two of the twelve plots have been established as a pollinator patch. More than twenty species of mostly native prairie plants have been established in the pollinator patch, which will attract many hundreds of pollinators over the season. And as part of the life cycle of the pollinators, some will lay their eggs on the leaves and stems of the prairie plants. The young pollinators that emerge from the eggs will overwinter in the stems, so that they will be available for the next season's pollinating process. Therefore we do not 'clean up' the dead plant material until spring, so as to give the next generation of pollinators a chance to survive and be ready for pollinating in the subsequent year.

In this pollinator patch, there will be plants in flower and developing seed throughout the season. Right now the following species are in flower:

Butterfly Milkweed

Common Milkweed

Oxeye, or False Sunflower

Pale Purple Coneflower
This next one is mostly finished flowering.
Foxglove Beardtongue

Wild Bergamot

And here are some of the insect stars of the show:

Eastern Calligrapher

Milkweed Bug
This next one, a type of Lady Beetle, is native. So many of the Lady Bugs we commonly see are not native, but have been quite prolific.
Ursine Spurleg Lady Beetle

Long-legged Fly
If you look closely through some of the plants, you may see the face of a little critter staring up at you.
This is a Milkweed Longhorn Beetle, and it is one of the more common beetles I've seen lately.

Not all invertebrate creatures are pollinators, but may be something that feeds on them, such as this spider. I'm not sure what species it is yet, but I enjoyed watching it sit on the stem, then suddenly race out to attempt to grab a small fly type of insect, and then retreat to this spot to wait for the next potential victim.

All of the above were photographed in the last couple of days. Here are a few other garden creatures that I have photographed in this pollinator patch at other times.

The first one is a Carrot Seed Moth. Although most moths are night fliers, it has been recognized that regardless of the time of day or night, some moths play an important role as pollinators.


Eastern Carpenter Bee

Hyaline Grass Bug

Pruinose Squash Bee

Seven-spotted Lady Beetle

It seems with the recent hot dry weather, pollinators and things like butterflies are less evident so far this year. Even things like Monarch butterflies, not a pollinator but certainly something that depends on plants, especially milkweeds, are not as plentiful as one expects. Some sources indicate that the overwintering numbers of Monarchs this past year in Mexico showed an increase from previous winters, suggesting the population of this Species At Risk was rebounding. I have seen a few here and there these last few weeks, but not a lot. Hopefully the weather adjusts to maximize the pollinators as well as Monarchs, if the weather is the difference maker and not the use of pesticides or other insect controlling technology.

Regardless, next time you enjoy those French Fries, tomatoes or whatever plant you are eating, take a moment to thank a pollinator for being able to do what they are designed to do!

Forest fun plus bird atlassing

 The bird migration has slowed to a crawl now but soon, the autumn migration will begin! Shorebirds that had nest failures in the arctic or sub-arctic may be back on their southward migration. Fortunately there are lots of other things to spend time looking for.

At Rondeau, I've wandered around looking for plants, some of which are extremely rare. Puttyroot, shown first, is not officially a Species At Risk, but it has been considered in that context in recent years.

Ash trees have taken a major hit in the last couple of decades, due to the Emerald Ash Borer, and while there is lots of regeneration of the species in various natural areas, Black Ash is now considered a Species At Risk. It grows in wet spots, usually in standing water. One of the key ways to separate it from other ash species is to look at the underside of the leaves. At the base, it is obviously hairy/pubescent.
Chicken-of-the-woods is a colourful fungus that can be seen from spring to fall. This is a small part of a large outcropping of this fungus that I saw on a large fallen log, along the Tuliptree Trail.
A short distance away, I encountered an Eastern Tiger Swallowtail having a snack.
Unfortunately this next item is not rare. It is Beech Leaf Disease, and is quite evident on the many American Beech trees at Rondeau as well as many other natural areas in southwestern Ontario. The future of this beech tree does not look good, as the disease can kill trees.

A quite rare plant species is this next one: American Ginseng. There are a couple of places where I have seen it, but due to its popularity for supposed medicinal purposes, it gets picked a lot. It will likely be in flower any time now.

This is what the developing flowers look like, at great magnification.

A species that is a general look-alike to the previously featured one, is this next one, known as Wild Sarsaparilla. It is widespread.
June is the month when Tuliptrees are in flower, and the flowers are impressive to say the least. It is an unofficial flagship species for the Carolinian Zone.
Fungi are more often seen in the damp, humid conditions later in the season, but some can be found when the right conditions occur even quite a bit earlier. This one is called the Eastern American Platterful Mushroom.

On sunny days, one might come across another Species At Risk, known as the Eastern Five-lined Skink, which is Ontario's only lizard.
And even during the day, one might encounter moths. This one is a Morbid Owlet....
...and this one is Three-spotted Fillip. I've been out to Rondeau with my black lights a couple of times so far, and will be featuring some of the moths that have visited my set-up one of these days.
On occasion you might encounter a black mass clinging to an American Beech branch. It is Black Sooty Mold, and forms as a result of a gathering of Wooly Beech Aphids, sometimes known as Boogie-woogie aphids due to their 'dance' when they feel threatened. They sip on the liquids in the branches and leaves, and secrete a large amount of liquid onto the branches, which then supports this mold.
As shown above, butterflies are out and about and once in awhile I will photograph some cooperative ones. This is a Hobomok Skipper, nectaring on a type of fleabane.

I spent a bit of time at McKerrall Woods, a municipally owned woodlot located a few kilometres northeast of Chatham, looking for bird action that could be contributed to the ongoing Breeding Bird Atlas. It is a woodlot that seldom gets visited by anyone else. At the small parking lot, there was lots of clover which attracted a rare butterfly, the Giant Swallowtail.

It clearly had had a rough time of it at some point, based on the damaged part of its hind wing. It didn't seem to hinder the flight of the butterfly, however.
Between the parking lot and the woodlot, one walks past a good-sized hayfield. There were lots of grassland birds....
Bobolink were fairly common, with at least 15 or more in the area, the males doing their courtship flight and chasing off competitors....
...while females took note in between carrying out their parental duties, carrying food to some nestlings.
Savannah Sparrows were even more abundant, shown below, but hard to photograph. I was hoping for a Dickcissel, but none were seen or heard.
Looking across the hayfield, I noticed this critter walking through, but at a distance.
Then it would leap and bound to make better progress passing through the tall vegetation.
There are no trails in this woodlot....
...but a few places that are not covered with vegetation.



That makes wandering through this woodlot a bit of a challenge, as there is lots of woody material under the dense growth ready to trip you up. A good walking stick is handy to have.

There is very little in flower now, as the leaves of the canopy have shaded the ground, and all the spring wildflowers have gone into seed production mode. This next photo is of a sedge, known as Gray's Sedge, not a common species but fairly widespread.

I did record a few bird species for the atlas, but due to the heavy canopy, did not get any photos to share.

I also have been at Clear Creek Forest Provincial Park in eastern Chatham-Kent. It is always a worthwhile place to visit, although the forest birds are hard to photograph. The wetland areas are more productive, photographically speaking.


A Turkey Vulture was resting on a broken stub above the wetland. The light was fairly harsh, against the mottled background. After preening for a few minutes, it flew off and joined some others.
Dragonflies are fairly plentiful in the various wetlands pockets here. This first one is a Dot-tailed Whiteface, aptly named due to the white dot on the tail, and the white face. This branch is a popular place for it to rest, as shown by the exuviae of other dragonflies using this stick from which to crawl out of an earlier stage of development before taking flight.
Next is a Calico Pennant with its quite distinctive colour and markings.
Blue Dashers were probably the most common dragonfly species that I saw. Some were just sitting...
...and presumably on the lookout for a mate with which to reproduce with. This next photo shows a pair of them 'in wheel', and preparing for the next step of reproduction.
A short time later, the female hovered over the water for a few seconds.....
...and then would regularly lower the tip of her abdomen to the water surface, depositing an egg onto a bit of vegetation. In a few days, the eggs will hatch, and the very young dragonflies will emerge and spend the first part of their lives underwater, before escaping the confines of their exuviae at the larval stage, as shown on the lower part of the Dot-tailed Whiteface dragonfly above. At that point, they will carry on with their life's adventures.

Stay tuned for more atlassing adventures, as well as some black lighting highlights!
