“Outside” monarchs

In 2017 there was so much monarch activity going on in the front yard, I honestly couldn’t keep up with all the eggs, caterpillars, and butterflies. It was a very entertaining change compared to the previous year, when I found only one caterpillar!

The season started really early, with a monarch laying eggs on May 26. I watched at least eight or nine of them (it’s not always easy to find all of them at once to count them) grow up into full-sized caterpillars ready to pupate.

Most of this action happened on the common milkweed. After spotting six eggs on one butterfly weed, I only found caterpillars there once or twice.

For the first time, I saw caterpillars eating not just the leaves of milkweed plants, but the flowers or flower buds, too. This one was likely one of the eggs from the May generation:

The monarch caterpillars, and the American Lady caterpillars, too, managed to ride out a hailstorm in mid-June:

In previous years I had planted swamp milkweed seeds in the front yard but never saw them appear. In the backyard, I had tried a couple of other varieties such as whorled and the “hello yellow” butterfly weed cultivar, but they were either eaten or overtaken by weeds. Last year, I decided to get serious about trying other milkweed varieties, to not rely too heavily on common milkweed, which often fades too early for the later monarch generations. So in June I picked up a few new milkweeds at the Landscape Revival plant sale: poke, prairie, and whorled (along with a couple non-milkweeds).

Five small potted plants in a row.

Some other time that I’ve already forgotten, I also picked up Sullivant’s and showy. I decided to fence in these new plants (the chicken-wire is not easily seen in this photo, though)…

… and that seemed to make a difference — not only did all of these survive, so did the whorled from years past that I thought was lost, as well as a couple of others that were not planted this year and so I’m not sure what they were. One was a butterfly weed that may have been the old hello yellow or may have been from seed that wandered over from the front yard. The others, I don’t remember at this point; I hope they come back and flower next year so I can find out what they are. But I know that they were milkweeds because all of these, old and new, planted and surprise, ended up with monarch eggs and then caterpillars!

One afternoon while I was giving a garden tour for my Butterfly Buddy, a monarch flew into the backyard to lay eggs. The most amusing part of her visit: she couldn’t figure out how to get over the chicken wire fence protecting the plants, so she first flew all the way around the perimeter, then landed in the middle of the fence and squeezed through one of the small wire openings! I’m really glad there was another witness for that because I’m not sure my husband believed me when I told him later (and I don’t blame him).

When I checked the plants later, I found out that not only had she picked this small showy milkweed, she chose a leaf that already had a hatchling! And on the same plant was a row of four lacewing eggs. When I went back to take a picture with a better camera, the caterpillar had already eaten the egg! That’s one way nature deals with competition, I guess.

In all, I counted seven kinds of milkweed in the backyard, and this monarch laid an egg on six of them! I don’t know whether she also visited the common milkweed in the front yard, but this was a good validation for my plan to plant more species for later generations.

Poke milkweed:

Whorled milkweed:

Lots of very narrow leaves, one with a small white egg.

Unknown milkweed:

Are whorled milkweed leaves really big enough to support caterpillars? What happens when the caterpillars grow past, say, the third instar?

Nearly all of these plants were very small, not just the whorled milkweed (which is always small, even when fully grown). The exception was the poke milkweed, which was definitely not a first-year plant when I bought it. None were big enough, or perhaps it was that they weren’t established enough, to flower. I saw many caterpillars over the next couple weeks, but as I had worried, I saw none past the third instar. I’m not sure why: not enough food, too much competition, predators, moved to another area (though the front yard is quite far away for a little caterpillar), or something else.

Possible predator?

Following that generation, the next time I saw new eggs on the backyard milkweed, I collected eight of them to raise indoors.

After this amazing season of monarchs indoors and out, I’m hoping for another good local population in 2018 and will plan to order tags for the migration generation.

“Inside” monarchs

After a disappointing monarch season in 2016, I was thrilled to find many eggs and caterpillars in my yard in 2017. Some became temporary “inside” monarchs when I brought eggs indoors to raise the caterpillars and then release them outside as butterflies.

After seeing a monarch lay a dozen eggs at the end of May, and then finding many more eggs in the yard on the butterfly weed and on the common milkweed, I wanted to bring a few inside to watch them grow.

But wouldn’t you know that after weeks of my tending to the three caterpillars, and days of watching the chrysalises, they decided to wait to emerge until I was out of town? Fortunately I have a Butterfly Buddy who was more than happy to take the chrysalises…

…and send me updates on the three beautiful butterflies!

After that adventure, I took a break from raising caterpillars during the busy-ness of the summer. There was plenty of monarch activity in the garden during that time, which I will detail soon. I waited until after a five-day family reunion to begin again, and on August 7, I collected eight monarch eggs — then figured that was enough! Four of them had already hatched by the next morning. Not sure where two of the caterpillars are in this photo:

It was during this period that one of the caterpillars met a sad end when I wasn’t paying enough attention while cleaning the cage and grabbed a leaf exactly at the spot where it was sitting on the other side. I tried to console myself by noting that this one was much smaller than the others and not progressing well anyway, but it still was my fault.

In the midst of the raising of this group, on August 23, I found this newly hatched monarch caterpillar when checking out the progress of the front garden. (Good thing the common milkweed was still kicking out new leaves.)

August 30: My first release of the season!

A watched chrysalis never opens. Isn’t that how the saying goes? Even though there were three chrysalises like this on Sept. 1, I didn’t see any of them open!

But it was an exciting day, anyway, when the “three sisters” all hung out with me in the garden for the afternoon:

This one starred in a video chat with my nieces and nephew:

The next day, one emerged:

Two more were nearly ready that day, but in unfortunate timing, we were planning to leave for a weeklong trip the next day. This time I hadn’t planned ahead enough to pass them off to my Butterfly Buddy, maybe because I had optimistically thought they would have emerged sooner. So I did the next-best thing and tied the chrysalises to joe-pye weed plants so they could eclose outside and fly off on their own.

Luckily for me, one of them did emerge before we left, as I was waiting impatiently but not impatiently enough to pay close enough attention, and it was almost all the way out before I noticed. I’m always surprised at how quiet this process is; I was standing right there and didn’t hear a thing.

The other one apparently emerged safely, since we found an empty chrysalis when we returned.

Before the trip, I needed to release a caterpillar into the wild, too: the single one I found in late August. It was close to being big enough to transform into a chrysalis, but not close enough:

There’s no way that six days later I would find a caterpillar that had been that large, still in caterpillar form. But it was an odd coincidence to find a fully-grown caterpillar in the same area the night we returned:

Of course, I brought this one inside, too, and a day and a half later, it transformed:

On the autumnal equinox, he became my last butterfly of the season.

Final tally

  • 3 released in the first generation
  • 8 released in the migration generation

Camouflaged looper inchworm

On July 13 in the mass of black-eyed susans, I spotted more than a dozen different kinds of insects. The coolest was this one, which I believe is a camouflaged looper inchworm. Its destiny was to turn into a wavy-lined emerald moth.

This caterpillar chews off parts of plants and then attaches them to itself as a disguise.

Flower from above, with a caterpillar looped on the left side and several brown clumps attached to its body.

It was concealed so well against the flower’s dark-brown center disk, I’m not sure how I even spotted it at first!

Angled view of a flower, with a small brown clump on the opposite side of the center disk.

Though after I saw it once, I could easily find it again later the same day, and even the next day. (The accumulating quantity of frass also helped locate it.)

Caterpillar with its front end raised above the center disk.

Making its way around the ring of tiny flowers in the center disk of the black-eyed susan:

Almost finished the next day:

Side view again, caterpillar on the left side, no center disk flowers visible, but the caterpillar still appears to be eating.

I saw it crawling around a bit but unfortunately didn’t get to see any of the actual “gluing.”

Watch video on YouTube

Two more videos:

I kept checking back for this inchworm every day for a week and saw it many more times.

Top view of the flower, with the inchworm 'inched' at the top.

Top view showing two thick layers of camouflage:

Only the very top of the caterpillar showing, with two distinct ridges of material on its body.

Sometimes it was resting on a petal, and in these cases it looked nothing like a caterpillar.

Once I thought it was gone, but then found it again on a nearby flower. This time it looked different after it apparently re-covered itself with new material.

Flower in shade apparently underneath another flower, with the caterpillar 'inched' and some lighter brown or yellow material on its body in addition to the dark brown.

And this time I saw it eating the petals, too.

But after that, I didn’t see it anymore. Hopefully it made its way safely to its next stage as a cocoon.

Bees and turtlehead

I could watch bees crawl in and out of turtlehead flowers all day. Mostly it’s just bumblebees and honeybees that do this, because they’re big enough to open the flowers. And I see more bumblebees than honeybees here.

They force their way into the “mouth” of the “turtle” and rustle around inside for quite awhile, then exit and find another flower to repeat the process.

Video of a bumblebee from a few years ago:

Sometimes they need to stop and regroup after they exit, brushing the pollen off their antennae or eyes, I assume.

This flower has a honeybee inside, barely visible.

looking straight into the 'mouth' of a dark-pink flower, the bee is not distinguishable but the back of the flower is dark

This year, at first, I thought I had noticed a difference – bumblebees climb out backwards, while honeybees turn around and climb out face-first – but then I saw a bumblebee turn around, too. (And the video above shows a bumblebee that turns around, so I had seen that before.) In fact, I don’t seem to have any photos of bumblebees backing out. So much for that theory.

This one is my favorite: looks like it was quite the effort to squeeze out of this blossom.

Only a little hint of the insect inside.

Rudbeckia’s visitors

If I were giving out an award for the most social flower of the year, black-eyed susan would win. One fun day, I spent the morning checking and rechecking on them, noticing and admiring the diversity of insects that were attracted to the blossoms. About two-thirds of these photos are from that one day alone.

Bees:

likely a bumblebee on the right side of the center disk, facing downward

metallic green been in the same position

unidentified smaller bee on the left of the center disk, curled and facing downward

possibly a megachile, on top of the center disk, with legs full of orange pollen

Flies:

really big fly with hairs, possibly a tachinid, on top of the center disk

long-legged fly standing out on one of the petals

Flies that look like bees:

bee mimic with a wide abdomen

much smaller bee mimic, or hoverfly, hovering to the left of the center disk

Butterflies:

tattered monarch sitting on the right side of the flower

Eastern tiger swallowtail with wings outstretched, tilted toward the camera, on the right side of the flower

Bees and butterflies:

gray butterfly, possibly a hairstreak, on the left side, and a long-horned bee on the right, their antennae crossing in the middle

Lacewing:

Leafhopper:

small green insect tucked into the fold where the petal meets the flower's center

I don’t know what this is:

patterned brown insect with long antennae, climbing up a tall center disk

Inchworm:

skinny green caterpillar holding onto a petal with its head hidden behind the center disk

And my favorite find, a camouflaged looper inchworm:

curved brown caterpillar hanging off the right side of the center disk

(More about this camouflaged looper caterpillar.)

There was also this gruesome find — one dead bee on a petal, with two dead bees and one dead fly suspended below — but then again, a spider’s gotta eat, too. (I assume that’s what created this scene.)
