Tiny spring azure butterfly on a bluet flower

“April hath put a spirit of youth in everything.”

― William Shakespeare

April is the time of Hyacinth, tulips, apple and cherry blossoms, and, usually, April showers. Although we caught up from the drought of last year, this spring has been dry and we clearly need rain. Waking up on April 16, it was really no surprise to find it snowing as weather guessers reported it would get cold enough to turn last night’s rain to snow by this morning (but not in our area- ha!). In recent years there seem to be late snow events that have coincided with various trees and shrubs bloom time. Hopefully, this snow will not damage their flowers and buds.

Bloodroot flowers have mostly come and gone and bluets have just started blooming heralding the expected return of some of our thrushes, such as the veery. Tiger swallowtail butterflies often visit bluet flowers, as do many native bee species.

The six-spotted tiger beetles are out running along woodland trails. This small, predatory beetle is a brilliant metallic green, so it is hard to miss against a brown background of a woodland trail.

The other day while walking up a woodland hill trying to find a barred owl family, I came upon a really nice surprise. Just poking above the leaf litter were these tiny purple-blue flowers that were new to me. The plants each had unusual leaves with three rounded lobes. Flower and leaf stems were hairy, and this small area was the only place they could be found. They are Hepatica americana, round-lobed Hepatica. A native buttercup family member, they can bloom March-May and are found on leafy woodland slopes with higher calcium content than most of our Connecticut woodlands

Walking along the banks of a woodland double pond, there was evidence of recent beaver activity. A nice dam was getting some restructuring by the beaver, plus there were tree felling operations along the edges of the pond. Some nice moss was at the base of some  trees that so far are not in this beaver’s line of fire.

I found what I thought were clam shells along this woodland pond’s banks, but found out they are really the shells of freshwater mussels that were eaten by a river otter, muskrat or some other animal and left behind for people like me to find. Freshwater mussels spend the first part of their life as a tiny glochidium on a host fish. Afterward, they fall off and drop to the bottom of the lake, pond, stream or river bed where they remain partially buried. They help keep water clean by filtering it as they eat algae and other small water organisms.

Bee activity has been somewhat slow this spring, but recently a small Andrena nasonii ground-nesting bee was just emerging from under a landscape shrub where it had overwintered underground. This species often emerges when snow is melting and sometimes days before their foraging plants have flowered.. Most of our solitary native bee species are not aggressive, and this female rested on my finger for a while.

Native eastern red cedar Juniperus virginiana is in flower along the shoreline in Connecticut. Male and female flowers are cone like structures called strobili, borne on separate trees. Male cones are oval to egg shaped, with yellowish brown scales that hold the pollen, and they are located at the tips of 2nd year branches.

Turkeys are still stomping, hissing and fanning their tails, mourning doves have just fledged their first brood, kit foxes are playing around their dens and spring azure, mourning cloak and comma butterflies are flying around, so April has succeeded in its modest enterprise of pushing new life out of its winter slumber.

I agree with the sentiment of Hans Christian Andersen- “Just living is not enough… one must have sunshine, freedom, and a little flower. “

Spring is when you feel like whistling even with a shoe full of slush.  Doug Larson

Following a relatively mild winter, this spring has been a bit of a chiller so far. Forsythia in the north a yellow bud and central areas of Connecticut barely have yellow flower buds showing and star magnolias are just starting to show a few blooms. Spring may be slow to start, but at least it isn’t winter.

Spring peepers are singing, and have been for about three weeks. These harbingers of spring provide a cheery chorus for those fortunate enough to live near ponds. They were joined a couple of weeks later by wood frogs, who have a more throaty but equally welcome spring song.

Spring peepers live up to their name

Painted turtles, the first of which I saw in February on a 60 degree day, can be seen on warmer days sunning themselves on partially submerged logs and rocks. Spotted salamanders have already laid their eggs in vernal pools, and wood frogs should be doing the same now. Check out vernal pools for the eggs of these amphibians, plus you may see some immature salamanders swimming around before they develop lungs and venture onto land.

Spring azure butterflies, Celastrina ladon, have a single brood, and flight may occur any time between late March and early June here in Connecticut. This is one of our first butterflies to emerge from its chrysalis, and can be seen obtaining nectar from early spring flowers such as bluets and violets.

Another early flying butterfly is the Mourning cloak, easily identified by the upper sides of its large, chocolate brown wings that are edged with cream borders and lined inside that with lavender to blue spots. Imported cabbage white butterflies are arriving from their southern living quarters. This butterfly lays its eggs on members of the brassica family, which includes the wild mustards, including the invasive garlic mustard.

Migrating birds are slow to arrive, but the red-winged blackbirds have been back since early March, although some were even here in late February. Males arrive way ahead of females, which gives them plenty of time to select the best nesting sites in advance. Some warblers may fly through just before invasive honeysuckles leaf out. Palm and black and white warblers are some of the earliest to arrive. Palm warblers flick their rusty tail, much as phoebes do, and they move on northward to their breeding grounds. Many black and white warblers remain here to breed in woodlands.

Forsythia and star magnolias are just starting to bloom -later than normal this spring in northern Connecticut, but bloodroot and violets should be blooming any time now. These are important flowers for our spring pollinators. Japanese andromeda, Pieris japonica, has been blooming in some places since late March, and this is also visited by early spring flying bees. Along with pussy willows, this is a great plant for Colletes inaequalis, the earliest ground nesting bee which is active around the time  native willows start to bloom.

Check out streams for marsh marigolds and watercress, and dry sunny, woodland areas for native trout lilies that usually start to bloom in late April or early May. Red trillium, Trillium erectum, sometimes has an overlapping bloom time with bloodroot, depending on the weather.

Raccoons, foxes and many other animals may have their young from early spring through June. Some birds, including great horned owls, may have their young in late winter. Sometimes these owls use the nest that red-tailed or other hawks used the previous year.

While the central portions on the United States are having bomb cyclones this week that are bringing heavy snows and severe wind gusts, we should have snow here only in the form of a distant memory. I can live with that.

Spring has returned. The Earth is like a child that knows poems.

– Rainer Maria Rilke

This spring has arrived at a plodding, glacial pace. Several snows in April and chilly, gray days which far outnumber the anticipated sunny, warmer ones seem to have put nature into a low gear. Birds that normally would have arrived in early April, like chipping sparrows, were late arrivals. Forsythia bloomed later than it did the past few springs, and soils have remained cold enough to hold back lawn grass growth. But the cold weather can’t last, and we finally have seen a few sunny days this week.

Tree swallows arrived a couple of weeks ago, and barn swallows followed a week later. I always check out a nice swampy area along a road every spring when false hellebore is about a foot tall. This is when many migrating warblers start to come through on their way north. Two of the earlier arrivals are the yellow-rumped warblers and the palm warblers, which can often be seen together in good numbers as they catch insects on the fly. The loud drumming of pileated woodpeckers can be heard and barred and great horned owls should have nestlings by now. Canada geese should be sitting on eggs, with young hatching out in a week or so.

Bloodroot is now blooming, and before it is done, red trillium should also be blooming. Trout lily leaves are up, and its flowers should appear in a week or so. The early flowering azalea, Rhodendron mucronulatum, is flowering now with its welcome pink flowers. Bees were all over several plantings of this shrub on the UConn campus this past sunny Tuesday. Pieris japonica, or Japanese andromeda, Cornus mas and star magnolias are also in full bloom. Ornamental cherries are just beginning to bloom now and as the native black cherries begin to leaf out, look for tents made in the forks of branches by the Eastern tent caterpillars. Native bluets began blooming this week, and many native and honey bees, as well as early flying butterflies avail themselves of the nectar these tiny blue flowers provide.

Spring peepers have been singing like a glee club, and are a welcome white noise in early spring for those of you who live near ponds. In vernal pools, egg masses of wood frogs, spotted salamanders and American toads can be found now. Diving beetles and water striders are also active now. Our vernal pools support life stages of many kinds of insects and amphibians, and provide water sources for many animals and birds as well.

Red, or swamp, maples are already dropping flowers, while spicebush are just starting to bloom.  Snowball viburnums are leafing out and new leaves seen curling are probably signs of snowball aphid feeding. Look inside the curled leaves for these aphids. While not a cause of alarm for the health of the plant, it is a cosmetic issue. Redbuds are showing deep pink flower buds as are the larger ornamental cherry varieties like Prunus subhirtella, the weeping Higan cherry. When these bloom, crabapples are not far behind.

Japanese Andromeda, Pieris japonica, can bloom in March. This year it has remained in bloom through late April. Many bees visit its flowers.

More insects are becoming active now with the warmer weather. Look for the striking six- spotted tiger beetle along open woodland trails. Cabbage white butterflies are also arriving, and will lay eggs on native mustards and the invasive garlic mustards. The second generation may end up on your brassica later in the year. Mourning cloak and comma butterflies are out now, and look for swallowtails and the spring azure butterflies. Migrating red admirals and painted ladies usually arrive around the time of crabapple and invasive honeysuckle bloom. I can hardly (but must!) wait to see a swallowtail butterfly. To me this is a certain harbinger of steady, warm weather.

As you venture out this spring, listen for the songs of newly arriving birds, observe  insects as they go about their daily activities and enjoy the flowers that join together to make spring a poetic response to winter. Definitely a more charming repertoire in answer to winter doldrums than my own seemingly useless “ hurry up spring” song and dance…
