Walking Small

Nature will bear the closest inspection; she inspires us to lay our eye level with the smallest leaf, and take an insect view of its plain.

~Henry David Thoreau

The heat of summer is not my friend. It slows me down, saps me of energy, and makes me a little complacent I’m afraid. But, there is one saving grace – the abundance of minute life forms taking advantage of the green world that exists (in abundance I might add) outside our door. And, lucky for me, it doesn’t requite much effort to saunter around the yard, poking through the greenery, perusing the native plants, and looking for our tiny neighbors. I’ll most likely have several posts in the coming weeks that result from such forays into our yard jungle. Here are some recent discoveries…

Fall webworms leaf damage

Fall Webworms are a widespread moth caterpillar easily recognized by their often large silken tents covering leaves and the branches of many species of hardwood trees in late summer and Fall. In contrast, the Eastern Tent Caterpillar makes its silken hideaways in the forks of branches (of mainly wild cherry trees around here) in the spring. Females lay clusters of several hundred eggs on a leaf and the young larvae construct silk tents and feed on the leaves underneath, moving to new branches when they skeletonize one food source. When disturbed, they do a group fling and jerk dance to attempt to drive away any predators or parasitoids.

Northern Flatid Planthopper

An adult Northern Flatid Planthopper, Flatormenis proxima

We often find these distinctive planthoppers along the stems of many of our native wildflowers. This is probably the most common planthopper in our yard and is easily identified by its pale green coloration and the right angle of the rear corner of the wings.

Scudder's Bush Katydid nymph

Scudder’s Bush Katydid nymph, Scudderia sp.

One of my favorite tiny neighbors is the nymph stage of Scudder’s Bush Katydid. They are both gangly and bold in their appearance, with banded antennae to top off their comical look.

Blackened milkweed beetle showing pattern on dorsal surface?

Blackened Milkweed Beetle, Tetraopes melanurus

While checking out the milkweed patch, I spotted one of the many boldly marked insects that feed on this plant. It was a beetle with the bright warning coloration typical of insects that can feed on the toxins in milkweeds. This one had large, heart-shaped dark markings on its elytra (outer wings), identifying it as a Blackened Milkweed Beetle. When I looked up the scientific name, I discovered that the genus name, Tetraopes, means four eyes. This, and other members of the group of longhorn milkweed beetles, have compound eyes that are bisected by the base of their antennae (I could not find any explanation as to the possible benefits of this unusual eye arrangement). Every time I look closely at my little neighbors, I discover something new. Give it a try in your own nature neighborhood.

Bugs Galore

Every kid has a bug period…I never grew out of mine.

~E.O. Wilson, naturalist and author

The theme for summer camp last week at work was The Secret Lives of Bugs. We spent five days cruising around garden properties looking for bugs and other beasts. The kids had a great time and I managed a few pics of some of our finds along the way. Here are just a few of the wonderful creatures we discovered…

Longhorned beetle

A long-horned beetle brought to us one morning by one of the staff (click photos to enlarge)

Isopod

Campers learned about all sorts of “bugs”, including ones that had more than 6 legs like this isopod

Blue dasher dragonfly

The most common dragonfly at the Garden, the blue dasher

Spicebush swallowtail larva

One of my favorite bugs, a spicebush swallowtail caterpillar, still in its bird poop mimic stage

Eight-spotted forester larva

Eight-spotted forester moth larva

Oakworm moth just after emergence

One of the campers spotted this newly emerged oakworm moth (the wings are not yet pumped out to their full adult size)

Assassin bug nymph

honeybees from CCCG hive

One of the highlights of the week was a visit to a honeybee hive at the Carolina Campus Community Garden

honeybee with mite

A male honeybee with a varroa mite (that brown oval) on its thorax. These introduced mites are a major pest of honeybees.

bumblebee nest in box

We also learned about native bees from an NCSU entomologist. She brought a live bumblebee nest (above) and a drone box, where kids could let male bumblebees (drones) crawl on them (male bees lack stingers).

Mating Tiger Bee Flies

Mating tiger bee flies. These large flies are parasites on the nests of carpenter bees.

Signal fly - Family Platystomatidae

A signal fly earns its name from its behavior of waving its patterned wings back and forth as it walks, as though giving signals

Dragonhunter nymph

Sampling Morgan Creek yielded some nice bugs, including this unusual dragonhunter dragonfly nymph…

Dobsonfly larva

…and several of the somewhat intimidating hellgrammites (dobsonfly larvae)

Margined madtoms

We also managed some non-buggy critters, like these margined madtoms from Morgan Creek…

This gorgeous spotted salamander was found by another staff person as it cruised between buildings on a very rainy day

 

Summer Details

The beauty of the natural world lies in the details.

~ Natalie Angier

It has been a hectic few weeks at work with summer camp. One good thing is I am out in the Garden daily, and, anytime you are out in a place with that much diversity, there are plenty of things to see. I managed to take the camera out a few days before and after camp, and found some interesting subjects. Here are a few of the recent highlights…

Waved sphinx larva

Walnut sphinx pupa

The mummy-like pupa of a walnut sphinx moth (the antennae of the future moth can be seen outlined in the pupa as they curl down from the top into a point just above my finger)

Snowy Tree Cricket
Snowy tree cricket  (Oecanthus fultoni), male – this is the so-called thermometer cricket. The frequency of the chirps made by this species (made by the males as they rub their wings together) is considered a fairly reliable estimate of the air temperature. In the Eastern U.S., Fahrenheit temperature can be estimated by counting the chirps in 13 sec. and adding 40.
Yellow jackets on caterpillar

Yellow jackets dispatch a pink-striped oakworm to feed to their larvae

Rabbit running in Garden

One of the many bunnies that reside at the Garden (quite happily, I presume)

Black-spotted prominent

Gardener’s friend – a black-spotted prominent larva feeding on lespedeza

Black-spotted prominent rear end

This caterpillar practices deceit with its back end looking like a front end

Sassafras berries

Handsome Trig 1

A handsome trig (also called a red-headed bush cricket). This one is a male. The handsome part is self-evident; the trig part refers to the family Trigonidiinae, or Winged Bush Crickets.

Handsome Trig nymph

Handsome trig nymph (wings are still developing)

Dogbane Leaf Beetle

Planthopper - Rhyncomitra microrhina

A very pointy-headed planthopper (Rhyncomitra microrhina) that we caught while sweep-netting

Rear end of tulip tree silk moth cayerpillar

All is well that ends well…the rear end of a tuliptree silk moth caterpillar. Eggs were laid by a female on 5/18/17, hatched on 5/30; caterpillars had all pupated by 6/29; first adult moth of this summer’s second generation emerged on 7/20. This new generation will overwinter as pupae.
