Caught in the Act

How brazen! Out in the middle of broad daylight! The nerve!

We suspected this was the culprit responsible for the artificially dwarfed hollyhocks, but now it was ripping its way through the hostas as though they were so much lettuce.

I must admit I felt no sympathy for it as it twitched and shook itself at the insects trying to make the it their meal. Ha - fair play. You eat our garden, and the insects can have you!

In the Garden

I zipped out into the butterfly garden this afternoon for a quick break. A tiger swallowtail fluttered by (we've had lots of these this year), but didn't hang around for a portrait session. Instead, I got this little fellow.

When I went back inside, I combed three butterfly books to try to identify it. After many frustrating minutes, I found it: an Arctic Skipper (Carterocephalus palaemon). In Butterflies Through Binoculars it is described as "a small, but choice, gift from the north." Isn't that delightful? And it is small, measuring less than an inch high when its wings are folded. I particularly like the banded antennae.



Our garden columbines are also in full bloom. While we have some variations in color, they are all in the pink/burgundy family. I love flowers with unusually-shaped blooms, and columbines certainly qualify.

Looks like we aren't the only ones interested in peeking inside the flower!

The Painted Daisies (Chrysantemem coccineum) add a vibrant splash of color to the gardens:

And this is the first year our Baptista (False Indigo, Baptista x varicolor 'Twilight Prairieblues') has bloomed! I almost mistook it for a lupine when I walked by.

Another Batty Update

I just spoke with Carl, the DEC dude who is heading up this bat survey, and here's the latest scoop from data that are coming in.

Reports are showing lots of Big Brown Bats (Eptesicus fuscus). The theory here is that because these bats have different overwintering strategies, they are doing okay and have so far been unaffected by WNS. It seems that many Big Browns overwinter in man-made structures (attics, barns, etc.) and as such have avoided the contamination in the caves.

They are also picking up lots of Hoary Bats (Lasiurus cinereus), as previously metioned. He didn't mention if Silver-haired (Lasionycteris noctivagans) or Red (Lasiurus borealis) Bats were showing up in the data.

Additionally, they are getting few if any hits of the small myotis, that is to say, the Little Brown Bats (Myotis lucifugus). These are the ones hardest hit in the caves, so this does not come as a surprise.

Amy, Steve and I did another bat survey route on Sunday night down in Indian Lake. Twenty-two miles that route was, along a road that was VERY rocky. We didn't get very many hits, which surprised us since the route had several bodies of water nearby. Again most of our hits occurred closer to human habitation (street lights).

We have one more route to run: Pottersville to Weavertown. Then the equipment will be sent on to the next volunteer on the list.

I'll pass along other data as they come in.

More Bats

Last night was Night #2 for the DEC Bat Survey for which I am volunteering (see "Help the Bats" post on 9 April). My fellow volunteers and I have been very pleasantly surprised that we have been picking up bats with the detector/computer set-up.

Our first night (Wednesday) we drove from Goodnow Flow down Route 28N and around the research loop at Huntington Forest, an almost 22 mile route (at 18 mph). Most of the hits we got were under the street lights along 28N (no surprise there).

Last night we started up in Tahawus at the Upper Works (known by hikers as the southern entrance to the High Peaks Wilderness Area). This was an easier route to drive because it is blessedly paved! So down the Tahawus Road we went, hanging a left onto the Blue Ridge Road, completing an 18 mile route. Again, we had several hits, mostly near bodies of water, which is where we expected to find them.

The data we (and other volunteers) collect will be reviewed by DEC, the sonograms examined to determine how many bats were located and what species. While I am no expert, I do have a tape I acquired a few years back of bat calls, and I suspect we encountered at least three, maybe four species between the two nights. Without having that tape handy to compare the recordings to what we are hearing, I can't tell you which species; we'll have to leave that to the DEC folks.

New York is home to nine species of bats: Little Browns, Big Browns, Indiana Bats, Red Bats, Hoary Bats, Silver-haired Bats, Small-footed Bats, Eastern Long-earred Bats(or Keene's Myotis), and Eastern Pipistrelles. Three of these (Reds, Hoarys, and Silver-haired) are solitary tree dwellers that migrate south for the winter. So far, as far as we know, they have not been affected by White-nose Syndrome (WNS).

Of the remaining species, the Indiana Bat is already classified as a Federally Endangered Species, and the Adirondacks host the fourth largest winter colony of this species. As you can imagine, there is great concern about this species and the impact of WNS upon it. Mortality surveys, however, indicate that Little Browns have been impacted the most. Little Browns are historically a very common species, but as WNS progresses, we may witness the fastest transition from common to extinct this planet has seen.

We plan to do a second survey on each of these Newcomb routes, just to gather as much data as possible. I am also scheduled to do a run down in Indian Lake, which I will be scoping out this weekend. All we need are a few more clear nights.

Beautiful Moths

Toby made a great find this morning. We were on the third leg of our morning walk when suddenly the ol' pooch perked up and made a beeline to the roadside. There in the grass, barely moving, was a lovely cecropia moth. I picked it up and set it on my shirt - a beautiful living brooch. As we continued our walk, the moth started to shiver and shake - no doubt trying to warm up after a cool night. I noticed that its left hindwing had a tear, but otherwise it looked fine. When I got home, I set it in a box where it would have a quiet, dark, secure place to sit until I got to work. Suddenly it was active - must've warmed up. I could hear all sorts of scratchings and flutterings from inside the box. After about ten minutes it was quiet again. When I got to work, I grabbed the camera and the box and went outside for a photo shoot.

As you can see, the cecropia, which is one of the silk moths, is a large insect.

How beautiful it is with that large, striped furry body!

The large feathery antennae indicate that this is a male. With the silk moths, the males emerge before the females, so they are rarin' to go when the females come out. Like many other moths, he doesn't have functional mouthparts, so he won't be eating. Instead he'll live off his fat reserves, hopefully finding many females with which to mate before the fat supply is gone.

I couldn't resist getting a close-up of the wing - the colors are just stunning.

Next we have a polyphemus, which we found a couple days ago. This male has obviously seen better days:
It was still alive, but the ants were already trying to make off with it. So, I picked it up, blew off the ants, and took it home, where I stuck it in the freezer. This is the humane way to quickly end a moth's life. Like the cecropia above, this is a male - note the large, feathery antennae.

The centers of the wings' eye spots have lost their scales and are transparent. Moths have these eye spots to help deflect the attention of predators. Hopefully the potential predator sees the eye spots and thinks it is looking at something else entirely, like an owl, for example, and leaves the moth alone.

Luna moths, another of our native silk moths, also have eye spots, but the ones on the forewings are small. I found this wing back in early May. It is in pristine condition, except for the fact that it is no longer attached to the moth. "Luna moth green" is one of my absolute favorite colors.

According to my friend Lydia, who is the moth and butterfly guru at the Paul Smiths VIC, we should be starting to see the females silk moths fairly soon. Their antennae are not large and feathery, so you can easily tell them apart from the males. Lydia says that if you find a female silk moth, the odds are very good that she is gravid - heavy with eggs. While it is possible for you to raise her young, if she is not injured you should let her go and complete her life, laying her eggs on the appropriate host plant(s).

If she is lightly injured (say with a torn wing like the cecropia here), you can place her gently in a paper bag, close the top, and set it aside in a quiet place. She will lay her eggs within the bag before she dies. The eggs should hatch about 12 days later (sooner if it is warm). You will then have a bunch of silkworms to raise; be sure you know what species you have so you can provide the right food for them. After they grow up and pupate, you can release the adults to continue their species's survival in the wild.

Ellen to the Rescue!

This morning I helped an enormous snapper cross the road. (You never have a camera around when you need one.)

I could see her lumbering across the road from a few hundred feet away - she was that big. As soon as I stopped the car, however, she stopped moving - not a good sign. I didn't have my shovel in the car, so I had to improvise. I grabbed the window scraper (luckily with a long handle) and tried to coax her to the roadside. She was having no part of it. She turned to face me and continually struck out. The speed at which these animals can strike is stunning! She refused to budge.

So, I scoured the back of the car for a Plan B. Found a box. I put the box in front of her and tried to push her across the pavement. She opted to crawl into the box (sort of). With her head safely out of range and surrounded by cardboard, I grabbed the flap of the box and tugged her to the grassy verge. Getting her out of the box now became the challenge. I finally had to upend the box, and there she lay, the proverbial turtle on her back. I went back for the window scraper and flipped her back upright.

I lucked out: only two other vehicles passed during this time. The first was a commuter/tourist in the other lane, who slowed down, stared, and drove on . The other zoomed up behind my car and turned out to be the educator from next door - he gave me the thumbs up for helping a turtle and zoomed around me towards the office. I was very lucky no log trucks came by (considering I had several pass me earlier in the morning).

Well, I've done my good deed for the day! I guess I can go home now. :D

It Came from the Bottom of the Lake

Okay, not quite, but we were looking for aquatic invertebrates in a frog pond and at the outlet of Rich Lake - close enough.

This group of seventh graders had a great day for insect dipping. First we sampled at the outlet, where rushing water and rocking rocks made dipping a challenge. Mostly we had to turn over rocks to find the critters.

Stonefly nymph cases abounded - they were on every rock and all over the grasses along the shoreline! Here is a close-up shot of one; note the crack in the back, from which the adult (see below) emerged.

Some of the kids were really into it, while others preferred the view from the shore.

After a leisurely lunch on the bridge,

we moved to the Frog Pond. What a difference: still water, lots of emergent vegetation. Frogs galore, one tadpole, and many minnows.

This scarey-looking thing is a giant diving beetle (water tiger) larva - the mouthparts are impressive:

These guys were communing on the cattails:

All in all, it was a successful outing. Chaulk another one up for insects!
