dragonfly - Widow Skimmer

The widow skimmer Libellula luctuosa), part of the group 'king skimmer' dragonflies. It has large bulky body (compared to other species odonata) with large heads.  This is a juvenile, with yellow with brown stripes.; when adult it will have a steely blue body.  Wings are transparent, but marked with prominent black basal bands.  Widow Skimmers are found commonly in muddy substrates, or still bodies of waters such as ponds. They prey on other smaller insects like mosquitoes.

bee on asters

 

The asters are abuzz with pollinators.  While standing among the wildflowers, I hear the buzzing as loud and pleasant.  There are many Panicled Aster Symphyotrichum lanceolatum plants in the riparian area around the pond.  The nectar and pollen of the flowerheads attract many kinds of insects, including honeybees, bumblebees, wasps, flies, butterflies, skippers, and beetles.  I have not seen any Wild Turkey here, but they feed on the seeds and foliage of aster plants.  Maybe some day . . .

bugs by the pond






If you would walk around this pond today, you might see many insects on the flowers.  

Along with searching for a meal, they also carry pollen from plant to plant. Pollen allows the plants to set seeds and reproduce more plants of the same kind.

Here, a Leatherwing on Boneset flowers. This insect also eats eggs and larvae of other insects.

Below, a Ladybug sits on milkweed flowers.  Ladybugs eat aphids, scale insects, and other plant pests.

mountain mint



Mountain Mint Pycnanthemum virginianum  is blooming in the marsh around the pond.  
It offers very fragrant leaves and many small flowers that attract bees, wasps, flies, butterflies, and beetles.

Perched on the windowsill.  Looking in at us.

galls on goldenrod

 
Now, in June, the typical insects are laying their eggs in the goldenrod stems.  The eggs will hatch larvae who will feed and grow inside the bulge or 'gall'.

By autumn, the swelled galls with be more noticeable on the dried thinner stems.  The larvae will stay in the gall through winter, unless a bird pecks through to feast on them.  In Spring, those who stay hidden will emerge as adults.

The most typical insect causing galls are the Goldenrod Gall Flies Eurosta solidagnis, who completes its entire life cycle only on goldenrod. 

Last fall, I gathered several dried stems with galls.  They are such interesting shapes and colors, so they deserved to be in a drawing or painting!

widow skimmer

This dragonfly male 'Widow Skimmer' Libellula luctuosa shows off his handsome transparent wings with black and white structural coloration -- the production of color by microscopically structured surfaces fine enough to interfere with visible light.

The grass seedhead on the left is close to the camera and in front of the wing. But the rush stem behind the wing is showing clearly through the transparent wing while the skimmer rests, clasping that stem.

He is probably looking for prey -- other insects such as mosquitoes. To catch prey he will use his legs, and bring prey into his mouth with fangs.

bug on daisy

I was admiring the daisies.  A Squash Bug was also admiring it, close up!

bee swarm




On Friday, we noticed a blob of brown on a drooping branch on one the pine trees near the pond.  Close inspection revealed hundreds of Honey Bees clustered. The next day they were still gathered around that branch. We discovered with some research that when overcrowded in a hive, bees with divide their population then some will set out for a new hive. Scout bees look intensely for the new nest while the most of them wait together.  This probably saves energy and protects them by staying together in one place while the scouts scout.

By Sunday morning they had all gone from the tree branch, no trace left behind of their weekend stay.

boneset in autumn



Boneset Eupatorium perfoliatum has a stout hairy stem, and the plant's leaves occur along it opposite to one another.  In autumn, the flowers go to seed, and leaves turn a rich red-brown color.

The leaves are described as 'perfoliate' because each joins the opposite leaf around the stem so it appears the stem grows through one large leaf.  All parts of this plant are toxic and bitter. Birds rarely eat the seeds, but are attracted to the flowers for the many insects there.

damsel


 

Eastern Forktail damselfly. This is a young female who will change color as she matures.

grasshopper on coneflower


On the blooming coneflowers, a Two-striped Grasshopper Melanoplus bivittatus rests in the sunshine.  This grasshopper usually lives in sunny, moist, lush, weedy or meadow areas -- like the wetland around the pond. They eat a wide variety of plants, and sometimes also dead animal matter on the ground.  They require unsaturated fatty acids in their diet since these nutrients help keep their wings strong and rigid.

garden spider



Hidden in the grasses around the pond, this Yellow Garden Spider wove her web suspended from two plants two feet apart.  It looks like she has been successful catching lunch; the white item in her grasp is an insect wrapped in silk.  No brown paper lunch bags for this elegant creature, a Banded Argiope Argiope trifasciata.

planthopper

 


Planthoppers are masters of disguise. A green Acanalonid Planthopper, hiding on a stem, can look like part of the plant -- a seed pod, leaf, bract, or stipule. 

This one is only 3/8 inch long.  It was perched on a stem at the leaf sheath, probably sucking sap from the grass.  Planthoppers, true to their name, can leap many times the length of their bodies.  And they are very agile insects that can move easily forwards, backwards, or sideways.

green frogs on rocks






Usually, the frogs who live here sit on shore hiding among grasses looking for prey insects or invertebrates.

But when a rock is available, Green Frogs Rana clamitans prefer to sit in the sun and wait for a meal to present itself.

black wasp

 

I was surprised and apprehensive to see this big black wasp on a milkweed flower near the pond.  It was alarming because of its size (over one inch) but is not a pest to harm people. This Great Black Wasp Sphex pennsylvanicus, looks iridescent violet-black with smoky transparent wings that have a violet sheen. They visit flowers to feed on nectar and pollen; no harm to the plants. 

The female Black Wasp digs a burrow in the ground to reproduce her kind. She hunts katydids, paralyzes them, and places several in the burrow. She then lays eggs in the burrow.  They hatch into larvae. They have a ready meal, quietly growing into adult Black Wasps.

ladybug on Mountain Mint

This Mountain Mint plant supplied a meal for a ladybug.  Ladybugs, or Lady Beetles, are in the coccinellids family of beetles, not bugs.  Most are predators -- they eat smaller insects.  They prefer insects that happen to be considered pests on plants.  This includes mites, white flies, and scale insects, but especially aphids.  When the aphids are all eaten on a given plant, Ladybugs quickly head to another plant or area to find more of their favorites.

12 spotted skimmer


The pond area is home to several 
kinds of  dragonflies. 
The females lay their eggs on a plant in the water,
or just drop them into the water.
The eggs hatch after about a week,
when the creatures are called 'nymphs'.

Dragonfly nymphs live in the water while they grow. The length of this portion of the 
dragonfly life cycle is variable.
If the nymphs are not grown enough at 
beginning of winter they will remain
 in the water until spring, often beneath ice.
They feed actively and grow all winter 
to emerge as adults in spring. 

This is a dragonfly called 12-Spotted Skimmer, perched on a reed top in early August.

pennant






Walking along the shore near the pond on an overcast hot day, I noticed a dragonfly perched on a stem of Horsetail.

This is a Halloween Pennant Celithemis eponina dragonfly.  They usually perch horizontally like this, waving in the breeze pennant-style, at the top of vegetation.

At 1-1/2 inches long, this dragonfly would be a juicy meal for a predator.
