Life begins at night.
~ Charlaine Harris
It’s not just moths that I have been seeing out in the yard after dark. The new flash system has been out on a few nights with me as I wander the premises (carefully in case there are any Copperheads out and about) looking for what’s happening on the night shift. Here are some of the highlights of the late night crowd.
The sculptor of leaves, a May Beetle chewing its way through the foliage of trees and shrubs after dark (click photos to enlarge)
An Oblong-winged Katydid, Amblycorypha oblongifolia. Summer is the time for the katydids to come out and sing their chorus in the darkness. This is one of the katydid species that can occur in different colors other than the dominant green – orange, tan, yellow, or even pink.
A nymph of the Common Tree Cricket , Oecanthus sp., hiding on the underside of a leaf. An adult male tree cricket calls by rubbing the ridges of their wings together.
A common spider in our woods, this Spined Micrathena, Micrathena gracilis, is armored with stiff spines to deter predation. This is a female as they are much larger than males and are the ones that build the webs. Males probably use silk only during the mating ritual.
Annual or Dogday Cicada, Neotibicen sp. Although called “annual” cicadas, they actually have two to five year life cycles with some adults emerging every summer. Males produce loud high-pitched sounds by vibrating specialized round abdominal membranes called tympanums. Sounds can be as high as 100dB
The stars of my night-time strolls are the Cope’s Gray Treefrogs, Hyla chrysoscelis. This is prime mating season for these beautiful amphibians and we can hear their harsh trills from inside the house almost every night now. This one was shy when I approached and quit calling (his vocal sac is enlarged, but he is not inflating it for calling)
This one was not shy. Perched on a plant a few feet from one of our amphibian ponds, he was cranking out his calls trying to attract a mate. You can see the bright yellow on the inner thighs, usually visible only when the frog is moving.
Note the huge toe pads on this species, allowing them to expertly climb almost any surface.
I believe this is a female (because of the white throat). She was on the edge of one of our ponds, no doubt trying to decide which caller she liked the best. Once she chooses, she will approach the male and often touch him, and he will then grab her and, together, they will move to the water.
A small, loose cluster of eggs is laid at the surface of the water. They will hatch in a few days, with tadpoles developing into froglets in about 45 days.
Another pond dweller is easier to see at night – a Backswimmer, Notonecta sp. Note the long hind legs used like oars for locomotion and the upside down resting position at the water surface. Backswimmers are predators that capture prey with their front legs, and stab them with their strong beak-like mouthpart. They then suck out the hemolymph (insect “blood”) of the victim. They breathe by capturing air in a fine layer of “hairs” that cover their body.
Here is one of many larval Spotted Salamanders ( Ambystoma ) still living in our ponds. Eggs were laid in February and early March and the largest larvae now look to be about 2 inches long. They will soon absorb those feathery gils and leave the pond to find a home in the woods nearby. maculatum

Very Very cool to learn something about the variety of nightlife outside our doors. Always fascinating. MANY THKS
Glad you liked it, Molly. It is amazing what we can find close to home if we just look.
