Another beautifully mild day today, with our thermometer peaking at 17 oC (63 oF) in the sun mid-afternoon (actual temperature was somewhat lower, but not by a great deal). We’ve had a string of such nice days now. It looks like after tomorrow a cold front will move in and drop temperatures down for a few days, but by this time next week we’ll be back up again. I’ve been starved for balmy, sunny weather, I’ve been soaking it in these last few days.
So has the wildlife. I’m up to 12 species of moths recorded so far this season already. This seems to me like an extraordinary number for March 17, and I’m not sure how much of that number has to do with the string of warm days (perhaps we didn’t run into that last year?), versus me actually setting up and looking for them (I didn’t try this early last year because I didn’t want to waste my time if nothing was flying, since it was more of an effort when we were in the apartment, but this year since we’re in a house I can put the light out anyway and it’s not a big deal if nothing comes), versus simply being in a great place for moths (and everything else; I love my home).
Last night I got two moths which I took photos of this morning, after holding them chilled in the fridge overnight. Rather than just setting them up on the deck railing or on a sheet of paper or something, I hunted down a dead leaf that was still in good shape as a photo base. Most were starting to fall apart, or if they were still intact, they were curled up. Finally I found one that was whole, and mostly flat. When I picked it up and turned it over, I noticed a small white speck on the underside. It turned out to be a leafhopper. I think it’s a Red-banded Leafhopper, Graphocephala coccinea, also sometimes known as a Candy-striped Leafhopper. It’s very pale, and I suspect this may be because it had just recently emerged, and its exoskeleton was still soft (the colours in insects’ exoskeletons often strengthen as the shell hardens).
Also something I noticed today that I hadn’t over the weekend was a profusion of flies. They were ubiquitous in open areas where leaf detritus had piled up in the fall, such as the edge of our driveway and lawn, or the clearings along the forest edge. I’m not positive on its ID. I think it might be a Stable Fly, Stomoxys calcitrans, which is a common and cosmopolitan species. I was able to rule out House Fly by the veination on the wings, but that was about as far as I got. Flies are a group I’m content to leave to someone else’s expertise.
Edit: Kirk suggests in the comments that this is a Flesh Fly, family Sarcophagidae. So not even close to Stable Fly. I told you fly ID is better left to the experts.
I was intrigued by the discovery of the leafhopper, and the presence of all the flies, and thought perhaps during my walk with Raven today I’d take my camera and see what other spring insects I might be able to turn up. I wasn’t expecting much – after all, it’s only March 17 and there’s still snow on the ground in many places. But I might be lucky and find one or two.
I was surprised to discover a total of 13 individuals of 7 species today. Leafhopper and flies were #1 and 2, but species #3 was the above – fire-less fireflies known as the Winter Firefly, Ellychnia corrusca. The genus Ellychnia are all diurnal, and as such lack the light-emitting organs of most other fireflies (not much point, they wouldn’t be seen). They are also most commonly found on tree trunks, and indeed these two (plus one other) were climbing up the ridged bark of a big White Pine. The Winter Firefly, presumably taking its common name from its cool-weather tolerance and early spring appearance, also happens to be the largest firefly of the northeast by almost twice as much – the large one in this photo was probably about 18mm, perhaps 5/8″.
A couple trees away, sitting on the side of a hop-hornbeam, was this critter – a ladybeetle, but not the generic orange-with-black-and-white-“head” Asian Ladybeetle that we’re so used to seeing around the house and garden. This one is actually native, and discovering native ladybeetles is such a rare occurrence for me I could count the total number I’ve seen on two hands. Surprisingly, there are actually more than 480 species in North America, so I don’t know how much of my not having seen many is simply because they’re secretive compared to the Asian invaders, or because the Asian beetles are outcompeting them. This particular one, seeming the reverse in pattern from the usual black-spots-on-red, is called the Twice-stabbed Ladybeetle, Chilocorus stigma. You can see why the species was named such, but it’s a slightly morbid name, particularly when you consider the Lady in ladybeetle was actually a reference to the Virgin Mary.
There has been a general decline in ladybeetles on the continent, and in recognition of this the Lost Ladybug Project was started in an effort to build a database of ladybeetle sightings to try to help with monitoring these species (since it’s really hard for a couple of Cornell scientists to cover the entire continent). If you have any ladybeetle observations be sure to send them in!
I just happened to spot this guy sitting still in amongst the leaf litter while I was photographing a fly, not a foot away. It is a true bug with the scientific name Menecles insertus, and was easy enough to pick out in the Kaufman Insect guide by its all-brown colouring and pale stripe down its back. It seems to be a fairly common insect of the east, feeding on a range of deciduous trees. My guess would be that its brown colouring is an adaptation to a late fall and early spring adult stage, since the predominant colour in the landscape at those times of year is the brown of dead leaves. There wasn’t much info available in either resource I checked, though, and I’m simply hypothesizing that it overwinters as an adult since that would make such an early spring appearance easier.
I found two of these spiders, in two different spots. I think they’re a type of wolf spider, but I don’t have a definitive ID on them yet, either. They were scuttling through the leaf litter, and, aside from the flies, were the main source of eye-catching movement that I encountered. All of the rest of the insects required examining the ground more closely.
I also don’t know what this beetle is. It was just a wee little thing, less than half a cm (less than 1/4″) long, but a bright iridescent bronze. I had happened to kneel down to inspect a large rock with mica deposits in it, and as I was checking out the mica, a little beetle comes wandering up over the top of the rock in front of me, like he wanted to make sure he was counted.
Edit: In the comments, Ted makes this suggestion: “The beetle is a leaf beetle (Chrysomelidae) in the genus Graphops (subfamily Eumolpinae). It could be G. curtipennis, a common eastern North American representative, although there are a number of species in the genus that are difficult to sight ID.”
One other species I saw but didn’t post here was a diurnal moth, a small little tan guy, whose identity also remains unknown to me. It’s amazing how much time one can spend trying to identify things if one really wants to.
Finally, species #13, was these grasshopper nymphs (above and below). I found the green one first, and was quite surprised to discover a grasshopper. I didn’t notice until I got home that it was a nymph and not an adult. Part of the presence of grasshoppers so early is explained by this. It turns out they’re both Northern Green-striped Grasshoppers, Chortophaga viridifasciata. The species has two colour morphs, with both sexes occurring in both colours, but with females predominantly green and males mostly brown. Eggs are laid and hatch in the summer and over the course of the fall the baby ‘hoppers go through a few moults. The winter arrives while they’re still nymphs, though they may be anywhere from half-grown to nearly adults. They overwinter as nymphs and emerge early in the spring to finish growing. They’re usually the first species of grasshopper to be encountered as adults in the spring because they’ve got such a huge head start on development over other species that overwinter as eggs.
Total counts to date this season: 12 species of moth, 12 species of other insect. At March 17th! And spring (the official first day) not even here yet, it’s still four days away. I just can’t get over that. It looks like we’ll have to endure a few chilly days as a cold front moves through later this week and into the weekend, but we’ll be back up to these temperatures again next week. I wonder if I should wait till the 21st to declare spring finally arrived?

Oh to be in Southern Ontario again where the spring actually comes at spring time! In newfoundland we still have several feet of snow on the ground and will have snow well into May…even later on the hills. I usually don’t start seeing Robins until mid-April when exams start. We are in for a few sunny days, around 0 degrees, and maybe if I’m lucky (and if i have time to look) I will spot a few little critters on the snow or on a tree :)
The fly looks like one of the Flesh Flies, (Sarcophaga sp.).
Gorgeous photos. Can’t wait for spring to arrive here!
Thanks, Ted. I’m impressed you were able to ID it as specifically as you did given the not terribly impressive photo.
I don’t know how people do it, Melissa! I would be starved for spring by that point!
Thanks for the tip, Kirk. Flies are one of those groups that I really don’t know enough about to be able to sort out.
Thanks, Moe – can’t be long now!
