Butterfly Garden Progress Report Part 2 of 2

I shared Part 1 of this piece back in August. To recap, by “progress” I mean “how much wildlife has my habitat garden brought to my yard?” Last time I covered the most obvious category – butterflies and moths – and today I will focus on everything else. This all comes with the same caveat as before: I have no baseline wildlife survey to compare this to. I’m really just making a self-congratulatory list of wildlife sightings in my yard. Somehow, I am OK with that!

Before I move on, I do want to briefly mention four additional lepidopterans since August: the eastern comma (Polygonia comma), tobacco hornworm, aka Carolina sphinx moth (Manduca sexta), raspberry pyrausta moth (Pyrausta signatalis), and giant leopard moth (Hypercompe scribonia).

Insects, Non-Lepidopteran

Insects are an overwhelmingly diverse Class of animal life. I will never be able to identify to species every insect I find in my yard. There are plenty I can, though (especially with help). I’m able to put many more into the appropriate Family or Genus. Based on that, I am able to confidently list 90 insect species for my yard, including the butterflies and moths from the last post. That number doesn’t precisely represent individual insects confidently identified to species, although there is only a little fluff. “Fluff” in this case just means an insect I am very confident is a different species from any of the others included. For example, my garden was visited by a juvenile praying mantis for about a week last year. I can’t tell the difference between a Carolina and a Chinese mantis at that stage, but I can certainly say it wasn’t an ant or a caterpillar. Bees and wasps I can treat similarly: I can spot the difference between a yellowjacket and a bumblebee but am not well-versed in recognizing the individual species of each.

Spiders

Spiders are tough. When I get a photo to review, I am often confronted with notes like “identification to species requires dissection,” or find that I need to be able to see a very specific detail very clearly. Consequently, despite encountering certainly thousands of spiders I only have 16 species on my life list. Of those, only six have I found in my yard. They are: marbled orbweaver, basilica orbweaver, orchard orbweaver, woodlouse hunter, broad-faced sac spider, and Pholcus manueli. I can add at least four “fluff” species (a green crab spider, a jumping spider, a grass spider, and a brownish orbweaver) for a total of ten.

Other Invertebrates

Isn’t that specific? As much as I hate to lump all this together it’s so much more convenient than typing up categories for each individual kind of invertebrate. I am not enough of an expert to ID many of the included creatures precisely anyway. So what do I have here? The wood tick and house centipede are present for sure. I’ve found earthworms, pill bugs, harvestmen, centipedes, and millipedes of an unknown number of species each. At least three species of slug round out the list. That’s another ten animals in total, under the most conservative of estimates.

Birds

Thanks to eBird, I have very good data on the bird species I have spotted in my yard. It comes to forty-three species, and while none of these is particularly uncommon and five or so are merely flyovers, that feels like a pretty good number. And yet… just a few blocks away in Wheaton Regional Park birders have collectively tallied over 170 species. I’ve found more than sixty there myself. I won’t likely be attracting any, say, spotted sandpipers to my yard… but there is some room for improvement.

Mammals

This is a short and boring list (but try telling my dogs that!) Eastern gray squirrel, eastern fox squirrel, southern flying squirrel, eastern chipmunk, eastern cottontail, Norway rat, white-footed mouse, white-tailed deer, human, dog. Add some unidentified species of mice and bats, and it’s an even dozen. I do think the dogs somewhat cut down on the mammal population I might otherwise see here… I have after all come across groundhogs and foxes in the neighborhood and I know raccoons, possums, and skunks are about. As irritating as the rat population is, at least they’ve never made it inside.

Amphibians

An even shorter, but hopefully less boring, list:

And that’s the list! So to recap, that’s a grand total of: 90 insects, 10 spiders, 10 other invertebrates, 43 birds, 12 mammals, and 3 amphibians – 168 total animal species cataloged in my yard. All my instincts say that 168 is a big number, yet as I mentioned above more species of birds alone have been recorded in our neighborhood park.

Scat Cat Spat About Cat Scat (And Other Fecal Matters)

I confess, I’m just posting about the skill of tracking, specifically as it applies to identifying and interpreting animal scat, tracks, and other “signs.” I didn’t write a rap song, nor do I think Scat Cat ever “spat” about any such thing. I have one more confession: I do not have much skill as a tracker despite my interest in the outdoors. Learning more about it is on my bucket list, but here in my 30s I am discovering that the bucket is probably too small to hold everything.

I spend a lot of time outside, so I’m not particularly squeamish about animal poo. Yet, I’ve never been interested enough to overcome the ick factor and study it. It’s still poop. With regard to tracks, all of my attempts to learn have been stymied because it seems I rarely find tracks complete enough to give me a clue much beyond “some kind of bird” or “a smallish mammal.” When I do, it’s usually because I just saw the animal that left the tracks in the first place. Beyond those first two basics, other elements of tracking have eluded me as well. “What kind of bird is this feather from?” Shrug “A brown one?” “What’s the difference between deer ‘rubbing’ and ‘scraping’?” “Wait, aren’t those synonyms?” These are exchanges I have had. As far as scent cues go, I know what skunk spray smells like – that’s something, right?

Self-deprecation aside, I realized when preparing this post that I know more about tracking than I think I do. If you’re a naturalist, an outdoorsman, or whatever other type of person would read this far, you probably do too. A portion of this is subconscious and/or automatic and so I’m not really aware I possess the knowledge unless I really think about it. This applies to a lot of tracking skills, but – bully for you, readers! – the clearest and most numerous examples seem to relate to poop.

As I mentioned before, I haven’t made any sort of robust study of feces. Somehow, though, I seem to have a surprisingly vast scatological catalog. I’ve had dogs all my life, so I’m quite familiar with dog shit. Wild canines produce somewhat similar excrement. I’ve never owned cats, but my friends and neighbors have and I’ve been known to cat sit; cat crap is also a known quantity. I frequently hike or bike on multi-use trails (and I have marched in parades) so I can identify a pile of horse turds without a second thought.  Growing up I rode a school bus past thirteen cow fields each way (I know – I counted) daily, so many times I’ve glimpsed the nightmare apple pie crust that is a cow patty. Rabbits are common both as pets and in the wild, making their relatively innocuous pellets familiar. The occasional annoyance of mouse droppings in a home, office, garage, or shed has bred some familiarity. Then, too, I was recently acquainted with the dung of Norway rats when a couple took up residence under my house. In my efforts to rid myself of these visitors, I learned to distinguish their leavings from roof rat logs. Deer scat is easily identified because it is abundant in this area and distinctive. I’ve been to a pond somewhere that is a place in the world, so I know the green menace that is goose poop. Similarly beach trips have acquainted me with the milky paste ejected from seagulls and car ownership with passerine bird mess. One of my dogs once luxuriated in the pungent leavings of a black bear, so add that to the list. I’ve seen Jurassic Park, so I know that triceratops shit comes in “one big pile.”*

I chose to focus this post on scat because I kept coming up with examples – monarch caterpillar frass, aquarium fish poo, earthworm poop, the list goes on. What I’m really talking about, though, are unconscious, automatic observational skills. We all have them – and if pressed we can consciously call upon them. Don’t worry – I’m not getting mystical or piping the debunked theory that we don’t use most of our brains – there’s just a ton of information in our brains we don’t realize is there. Learning to tap into that is as important to tracking as acquiring the knowledge in the first place. Some of it’s even primal evolutionary stuff. If something looks, sounds, or smells odd it probably is, but most of us are way out of practice at interpreting those signals.

Another example: I used to think I was so terrible at differentiating birdsong that learning was a lost cause. I’m still no expert. But, I can pick out quite a few songs and calls now and it gives me a baseline to narrow my focus to the interesting ones worth listening to. Sometimes that’s even as simple as hearing a call I can’t place but know I hear all the time. I still can’t distinguish very well, without a recording, among the various types of sparrows or finches, but I can reliably identify the shrill call of the Northern cardinal, the song of a robin, the “mep mep” of a white-breasted nuthatch, the coo of a mourning dove, and several others. I can call to mind perhaps fifteen or twenty without thinking too hard. As with the silly list of waste product data, I’ve come to realize that much of this I already knew and it was just a matter of thinking hard enough to access the information.

Yet another way this phenomenon hits me is in the form of knowledge I have but can’t put a name to or express with the correct terminology. This most often relates to field observations which I haven’t formally recorded. It might be a spider with specific markings that I’ve seen a hundred times but don’t have a name for. It could be knowing that some mushrooms has a bump on top of its cap before knowing that it’s called an “umbo,” or that it can  help identify the specimen. It’s been plants I walk by every day, certain that they look similar in some way I can’t quite pick out but unsure if they’re the same species, or even related at all. Itemizing this nameless knowledge can be a useful exercise for a naturalist; it can start one on the right track toward knowing what you don’t know.

So, where was I? Right. Poop. I lied. I did write some (terrible) rap lyrics.

Scat Cat spat about cat scat
‘cuz the scat his brat shat left a splat where it sat
so Scat Cat spat: “brat, you best clean that scat stat
You can’t leave that fat pat just to chill where it’s at

It don’t matter clean that splatter ‘fore I rip you to tatters
Got me mad as a hatter it’s gon’ be batter up
and your body will shatter, ain’t no more pitter-patter
I’m a be your bad luck like you walked under a ladder

Then rat-a-tat tat I’ll come at you with my gat
This ain’t no tit for no tat, I ain’t gonna live like no rat
So brat clean that scat ‘fore I lay you out flat
and if you gonna do that next time put down a mat, drat!

*There’s no way that this was an accurate depiction of triceratops poo. This even bugged me when I was a kid. How is the top of the pile higher than the animal’s anus? Why does it look like an anthill?
