Question mark? Comma?

Kidding aside, those are real names of butterflies.  Just today I saw an eastern comma (Polygonia comma) in it’s summer form (black hind wings as opposed to orange hind wings for the winter form).  I am secretly hoping that the early abundance of different butterflies has something to do with the native wildflowers in my yard.  Or maybe they are just out earlier because of the warmer-than-usual weather.  It is probably the latter since eastern commas in summer form don’t normally show up until May at the earliest.  I am not the fastest photographer, and butterflies seem to know when I’m pushing the shutter on my camera and they have not been very cooperative.  I got lucky today and got a decent shot of this eastern comma as it was fluttering near the surface.  Eastern comma likes marshes and wet woodlands as its habitat.

juvenal's duskywing April 15 2012 The more showy butterflies such as the monarch and swallowtail may still be “waiting in the wings”, as it were, but that does not mean that Papilionidae or true butterflies are not represented this time of year. The spring azure has been fluttering about for a few weeks now, and just the other day I noticed a juvenal’s duskywing (Erynnis juvenalis) in the yard, trying to blend in with the soil and mulch. This particular species of butterfly is quite common in Massachusetts (although I noticed it for the first time this week), and can be seen from April to early June in or near oak woods. Unlike other species this butterfly is generally single-brooded, meaning that there is only one generation each year. The larva are fully grown when they overwinter.

about invasiveness

There are several definitions floating around on what it means for a species to be invasive. A lot of laymen and scientists alike tend to use “invasive” as pertaining to the agressive nature or habit of a species of plant or animal where the new species negatively affects native species, by means of crowding it out; competing for nutrients, food, water, and light; or directly consuming or killing it. That is definitely one way of looking at this phenomenon. I personally don’t subscribe to this narrow viewpoint, because in nature this behavior is a rampant and every-day occurence. Just think of two competing ant hills, or a big pine denying light to saplings of other species or even its own kind. Are there, or were there ever, “safe” and balanced eco-systems? I don’t think so – competitive advantage and opportunistic tendencies are part of the DNA of anything alive today, and even that is sometimes not enough to safekeep a future for the next generation. Today, just like eons ago, the threat could come from a thousand miles away or from the brush or thicket right next to you. Have we, as humans, facilitated invasive behavior? Undoubtedly, our highways and parceling up of ever smaller tracts of land have led to situations where a handful of trees, rather than whole forests are competing with other species under changing environmental circumstances. Now, before I go off on a tangent (and it may already be too late for that) I want to point out that I use “invasive” as meaning “not originating from the eastern US or Canada”, and having arrived here by some kind of human intervention – whether it was last week or 400 years ago. The definition I use does not indicate agressiveness or anything else pejorative. It simply means that a plant or animal is originally native to Europe or Asia. It wasn’t here before, and now it is. Simple. As for the plants thenselves – a good amount of them are quite docile, happy to get along with other vegetation, and more often than not they (as Chris from Forest Keepers pointed out) have nutritional and medicinal value that should make it worth our while to get to know more about them, instead of reaching for the Roundup… I am actually fine with having dandelion and other assorted European and Eurasian species sprouting up. It’s futile to try to get rid of them, at best you’ll get temporary reprieve, and using chemical means just creates havoc downstream and over time in many unintended ways. Maybe the more obnoxious species such as asiatic bittersweet are more deserving of the “invasive” label, but again I am looking at plants from the point of origin, not from any behavioral approach.

white trout lily April 15 2012I was able to acquire a few pieces of rootstock of white trout lily last year, and put them willy-nilly in the garden without having too many expectations about the outcome. After all, immature plants produce a single leaf and fail to flower – so at best I was foreseeing a lot of dappled leaves for the next few years. Only mature plants bloom. I was happy to see plants emerge that had two leaves. In white trout lily speak this means that those plants will produce a flower. Even without a flower present, the leaves make an attractive ground cover. Plants multiply rapidly by root offshoots and seed, but you should always expect more single leaves than flowers…

If conditions are right (dappled sun in the spring, heavier shade in the summer, moist and rich soils) the plant will spread and colonize an area over the course of several years… It’s a good companion plant to ferns…

twinleaf April 15 2012You may remember my post last year about the twinleaf plant (Jeffersonia diphylla), when I lamented the fact that I missed the ONE day this plant was in bloom. Of course I was aware that the flower lasts only a short time after blooming in April or May, and that it gives way to a green pear-shaped capsule with a hinged top. In 2011 a violent rainstorm “unhinged” the flower petals while I was at work, and I never saw this plant bloom. This time around, under perfect circumstances (no wind, no rain) the flower was present less than two days. But this time I had daylight and a working camera battery on my side. Talk about timing…

marsh marigold April 21 2012Marsh marigold (Caltha palustris)  is a European and North American plant of the buttercup family. It is one of the most ancient native plants and I am frankly not quite sure whether it originated in Europe or in the Americas. It may have been growing here since before the last Ice Age and, after the retreat of the icecaps, it proliferated across the watery landscape.  It is still mostly found in wet places such as creek banks and low lying areas. I say “mostly” because I’ve seen it in uphill and dry areas as well.  I have them in a location that is likely much drier than they would like, but they are exposed to the harsh sun only part of the day, and they seem to be thriving even though the plants I have are still relatively small – some road crew had done some work on an embankment and marsh marigolds had been dug up, displaced and thrown by the wayside.  I am hoping these rejects will thrive in their new home. The leaves are round and glossy and the plant has large buttercuplike bright yellow flowers. The tops are reputed to be toxic but with boiling become edible and are often eaten as greens while young; the flower buds have been pickled and used as capers, and the flowers have been used for beverages.  Some individuals may develop a rash or skin irritation from touching the plant – I found out the hard way that I am one of those people.  Marsh marigolds bloom in early spring and are done blooming by late spring.

What a difference a week makes... The same plant, in bloom, on April 21 2012

It’s mid April and we’re having a repeat of last month’s heatwave, this time however I got to enjoy it with a few days off which was nice. 100 new tiny plants pop up in the yard each night, and all manner of insects are running wild in the yard. The paper wasps have returned to the exact same place in my kitchen window today; I think it is about the same time of year that they are appearing – however instead of building a nest and waiting around for a month, the queen is already accompanied by a couple other wasps and I get to see the tiny beginnings of the nest this time.  The first appearance of the wasps freaks me out, although I have never been stung (as long as you stay away from them they don’t bother you) I am not immune to being afraid of stinging insects.

I saw a couple bright blue butterflies this weekend for the first time, it was pointed out to me that they are spring azure butterflies – a few fat bumblebees too. At the beach in Brewster we saw hundreds of of seabirds - gannets, gulls and herons – no people or biting flies however – it’s a nice time to be on the beach. Went for a bike ride, the late afternoon weather was glorious. Drove to Gray’s Beach where we saw a firetruck and emergency vehicles. Some people got carried away and spent too much time in the water, one had to be treated for hyperthermia. Not sure what they were thinking, it is April in Massachusetts after all.

rue anemone April 17 2012Rue anemone (Thalictrum thalictroides) did it again – they are the earliest blooming wildflowers in my yard.  They must have learned some lessons from the hotly contested Republican candidate for President race, and trying to avoid lingering competition and wanting a decisive early win they produced flowers much ahead of last year (April 16 in 2011). The plan almost did not work – I have some white trout lily (Erythronium albidum) that are about to open up.

This year the rue anemone flowers are almost the first and only visible part of the plant.  There are few leaves, and the early heat and sun of last week must have forced them to bloom first and worry about details later.  This is much different from 2011 when the plants developed a good amount of leafy bushiness before producing the telltale white petals.

As for last week’s heat, it has been suddenly replaced by 20 degree weather and blustery wind.  Once again I let my guard down too easy and put my sweaters away too early.

Summer in March

This March we experienced some very odd weather. I had ants in my kitchen doing the exploratory investigations (showing up for a day or two then disappearing) that they did in late April last year; I saw a lone wasp in the area of last year’s wasp hangout (near my house) and lots of large bumblebees (mostly encountered these outside Boston). I am wondering if these insects  – or at least this generation – will make it through a cold snap if we get one. There isn’t alot out there about what climate change, or climate abberations, do to insect populations. Some articles mention they may breed more because they have a longer season, and that southern insects may move north; all mention the obvious  – that insects are definitely out earlier this year in New England. I have read that changing seasons could cause problems for the bee population – for example when the flowers bloom too early and the bees miss them, or perhaps the bees can be out too early and starve. I don’t know enough about all of these things, I can only report on what I see. We’re back to normal March weather now, so I think the insects are back where insects spend their winters for the time being.
