August 24, 2025: Pollinator Paradise

Sometimes one single plant can be a huge attraction to whole host of pollinating insects.

Thread-waisted Wasp on a Flat-topped Aster.

Like the Evening Primrose, when these asters started growing in the garden we thought they were weeds.  But curiosity inspired us to let them grow and see what developed.  The result is tall (up to six feet) wildflowers that have dozens of blossoms which attract everything from honeybees to tiny flies. 


I won't even try to identify them all, but here are some of the pollinators I found on a single plant at the same time.  










Aster seeds are also consumed by birds and they provide late-season nectar for migrating Monarch Butterflies.  Native to New England and growing well in hot and dry weather, it's an all-around excellent plant to let grow in your yard or garden - and you'll be helping pollinators which are under great stress these days.  Linda's woodland sunflower patch is another pollinator heaven.


Walking by it there's a loud buzz from the hundreds of insects visiting the blossoms, though they are predominantly bees - the sunflowers don't seem to attract the wide diversity of insects that the asters do.  


On the loon front I'm sorry to report that the survey crews have not been able to locate our younger chick Star, and we believe that he has been killed.  We don't know the cause, but another loon is a distinct possibility considering there has been a constant presence of non-resident loons on the lake.  We also know that the parents had been leaving chicks alone, tucked in against a shoreline while the parents go out to fend off other loons.  Earlier this week I watched our resident north territory male defend his territory from four other loons.

Letting intruders know this territory has been claimed before they get any ideas about next summer.

Escorting them out of the cove.

"And don't come back!"

But we can take solace that the larger chick, Spangle continues to thrive.

Starting to look like a juvenile loon now.

She is not safe yet though as she remains susceptible to attack by other loons, though with only one chick to defend, she will be better protected than ever.  We'll continue to hope for a positive outcome.  


Birds with larger broods than loons have better prospects for some of their chick to survive simply due to the numbers.  


I'll close with a bright greed katydid visiting our house. 


These are perhaps the prettiest of the insects in the bush cricket family, and the one makes the distinctive "katy-did, katy-didn't" sound by rubbing it wings together.  They can be distinguished from grasshoppers by their very long and thin antennae, often longer than their bodies. 

Grasshoppers have shorter and thicker antennae.  Katydids are mostly nocturnal, but this one was out in the morning sun for some reason.

Next week I'll be looking for late summer wildflowers.  Here's a preview of what's to come:

Perley Everlasting - another member of the aster family, but with a much different flower.

It should be a good week to walk through fields and along country roadsides.

July 30, 2023: Cross Orb-Weaver

Often in the summer a dock spider takes up residence in our boat, but this summer a different arachnid took over that real estate.

A cross orb-weaver spider (Araneus diadematus) secures her prey. 

Females of this species make the web, and I couldn't tell what kind of insect she caught because she had already killed it and had it all wrapped up in silk - but it's large, maybe a deerfly or a bee.  

Spiders have the ability to create different kinds of silk for different uses, such as a strong silk for the frame of their web (which they walk on) and a sticky silk for trapping prey.  It's not the first time we've had an orb-weaver on the boat and it seems that only one type of spider will live there at time.  There's even been a third kind of spider some years, a long-jawed orb-weaver, including earlier this summer, but that one has disappeared now that the orb-weaver has shown up.  There are several webs on the boat and the dock, and I feel a little guilty disturbing them when I use the boat, but she doesn't seem to mind - there's always a new one there the next morning. 

Two webs span from the dock to the boat, one on the bow, one on the stern.

I'm assuming the same spider owns all the webs because I only see one spider, with the other webs unoccupied.  Yesterday morning the homeowner appeared to be sleeping in late, right in the center of one of the webs.
Or maybe she's subduing another dinner guest.

She was quite exposed here.  When this kind of spider feels the need to hide, perhaps off in the bushes beside the web, they construct an early-warning system to let them know when they've caught something in their web.  They run a strand of silk from the web which they hook onto one of their appendages.  When something strikes the web it vibrates the strand so they know they have a customer and will run out quickly to subdue it before it escapes or damages the web by flailing around.  The spider bites the trapped insect to inject venom which quickly kills the prey and also starts to dissolve its innards for easy consumption by the spider.  Kind of a gruesome process, but very effective.

Sometimes a spider will get lucky and trap a real feast such as a dragonfly, but not this one:

Yellow-sided Skimmer (Libellula flavida)

This pretty yellow-sided skimmer was resting on a blueberry bush right next to one of the spider's webs.  The dark wingtips and the slight amber coloring on the leading edges of the wing add to the beauty of this species of odonata, especially in the soft evening sun.  Early in summer males and females have the same coloring, but as the summer progresses, males develop a powdery blue coloring called pruinose, a fine dusting on their abdomen.  [Ref: Yellow-sided Skimmer New York National Heritage Program]  It's not known why this happens, though it may be to reflect sunlight to reduce heating, a useful feature this past week.  I've seen these blue dragonflies but didn't know what they were.  I'll watch for them this summer.

I saw another dragonfly with almost the inverse coloring on Linda's hibiscus plant; I haven't been able to identify this one yet.


Dragonflies are ancient animals.  In the Permian period (275 million years ago) the largest species had a two and half foot wing span which made it the largest insect known to have existed on Earth [Ref:  Largest Extinct Insect, University of Nebraska].  Like many animals they have shrunk dramatically in size over time, but some dragonflies are almost as large as some birds.  We sometimes see a hummingbird drinking nectar from the bright red hibiscus blossoms but rarely get a picture.  It was Debby Crowely that took this fabulous photograph of a ruby-throated hummingbird.

In case you're wondering, Debby used a 1/1000 of a second shutter speed to capture that image.


The loon update has LuLu and Checkers growing by leaps and bounds.  

LuLu

Checkers

Lulu is noticeably larger than Checkers, and having lost more of her baby down, shows a fair amount of juvenile plumage.  Here's a comparison of the siblings.
Checkers on the left, LuLu on the right.

Mom spends lots of time with them, giving them their daily lessons.

Morning Lessons.  Note the band on mom's left leg.

These pictures from Debby explain any mystery of how these chicks can grow so quickly.

Yet they still have a ways to go before they grow into those huge webbed feet.

LuLu showed off her bright white chest while she waved at me.


With August almost here, the predominant colors of the flowers are changing; this week, yellow was the word.

Woodland Sunflower

Bees like yellow.


Soon the goldenrod will bloom, adding acres of gold to the fields around the Lakes Region.  It will be a reminder that summer is progressing, and that we should enjoy these long summer days, no matter how hot and humid.

The coming week looks to be better.
