goldenrod

 

To complement all the blue and purple flowers around the pond this week, the Goldenrod has unfurled its blooms.  Solidago species, commonly called Goldenrods, are in a genus of more than 100 species of flowering plants in the aster family, Asteraceae.

Goldenrods are often blamed for allergies, but they have sticky pollen and rely on insects to move most of it.  The wind borne pollen of ragweeds and pigweeds are to blame for 'hay fever' in late summer.

These plants are habitat for a large number of insect species. Blooming in late summer, they are a critical nectar source for many bees, butterflies, and moths to fortify themselves before freezing weather comes.

swallows

There are two kinds of swallows that regularly hang out near our pond.  Both species are aerial insectivores, which means they are so agile they can eat and drink all they need while flying.  They “swallow" food with their mouth open as they soar through a group of flying insects.  They dip their beaks to sip water as they glide low over a pond or lake.  They eat mosquitoes, flies, grasshoppers, beetles, moths and other flying insects in mid air.  Small birds with long wings, they can make sharp turns at high speeds in order to catch hundreds of insects each day. Swallows are most often a welcome sight with their voracious appetite for flying insects – a good mosquito control method.

Tree Swallows Tachycineta bicolor are iridescent blue with a white front and underparts  nest in cavities . . .  old woodpecker holes or a nestbox like Bluebirds.

The Barn Swallow Hirundo rustica has a deeply forked tail, dark feathers and rust colored throat and  under parts.  This 6" long bird lives in farmlands, suburbs, and wetlands. Because they make nests of mud in barns, on ledges, or under eaves, the location of their nests sometimes make them a pest.

emerged

We have been watching the cocoon since it was re-attached to a willow stem two days ago.  Today the Polyphemus silk moth Antheraea polyphemus emerged.  This adult will live 3 or 4 days. She will not hunt or feed, only seek a mate in her short existence in this form. The life cycle will start again when she lays eggs; the eggs will hatch caterpillars that will eventually cocoon to become as handsome as this adult.  Look closely -- the 'eye spots' are as transparent in real life as they look!

what is it May 2020

I found an unfamiliar object on a twig laying on the ground near the pond. Deer have browsed the willow shoots in that area, and this was cut but left behind. The object seemed like a gall or growth rather than a seed pod.  It has dried leaves curled around it, and looks to be attached to the twig with a web-like or woven material.  I asked my friends on Botanical Wanderings for ID help -- it is most likely the cocoon of a native silk moth. If so, it should emerge in the next few weeks. Hopeful, I tied it to a sandbar willow branch near where I found it, since willow a host plant where giant silk moths lay their eggs.

My knowledge of garden pests seems to have evaporated over winter . . .
This 2-inch-long small green worm with a silvery stripe would usually be difficult to detect on green plants, but this one was on a native Penstemon plant with rich maroon stems and leaves.
Since there is so much concern about loss of butterflies and bees, I want to encourage any that I can.
To my chagrin, I realized it is a cabbage looper! 
This caterpillar is the larval form of the white cabbage moth, Trichoplusia ni.  They love plants in the veggie garden -- broccoli, cauliflower, kohlrabi, cabbage, collard greens, potato, tomato, spinach, and cucumbers.  They typically eat holes in the leaves and hide out on the bottom side of the foliage.

A sunny late-summer afternoon at the edge of the woods . . .  this White-lined Sphinx Moth Hyles lineata joined the butterflies scouting nectar from the various blossoms.  At first we mistook it for a hummingbird; it gracefully flexed its body and "tail" as it moved among the blooms.
