The insect world is seemingly endlessly diverse, and always fascinating. "Bugs" make the world go around, and natural systems would collapse without them. Insects also make for great macro photography. Here's a few images from recent outings.
Ants tend the caterpillar of an Appalachian azure butterfly,
Celastrina neglectamajor. Caterpillars of this species eat only the flower buds of black cohosh,
Actaea racemosa. A bud cored by the caterpillar can be seen at right. The somewhat shapeless greenish-white blob of a caterpillar has its tiny brownish head to the left. Ants (species unknown to me) swarm the larva. This batallion will stay with the caterpillar, defending it from would-be insect predators. In return they are rewarded with nutritious "honey dew" secretions from the caterpillar. Shawnee State Forest, Scioto County, Ohio, June 16, 2019.
Tiny Buck's plume moths,
Geina bucksi, dangle from the flower of a poke milkweed,
Asclepias exaltata. These moths, which resemble mosquitoes when in flight, are smitten with milkweed nectar. We saw hundreds of them swarming milkweed flowers on this day. Shawnee State Forest, Scioto County, Ohio, June 6, 2019.
A ferocious "bumblebee" indeed! A robberfly in the genus
Laphria (possibly
L.
thoracica) perches atop a black ash leaf. It is the consummate bumblebee mimic, and probably is often dismissed as such. When a suitable insect victim wings by, the robberfly whirs into action, overtakes and grabs the victim, and injects it with its hypodermic proboscis. The prey is quickly debilitated by neurotoxins and is taken to a perch to be consumed. Cedar Bog, Champaign County, Ohio, June 12, 2019.
A female ebony jewelwing,
Calopteryx maculata, pauses briefly in a dim forest understory. These dark-winged damselflies are common sights along wooded streams, and are distinctive in their fluttery flight. Seen well, they are marvels of iridescence, as shifting light brings out different colors in the animal's body and wings. Scioto Brush Creek, Scioto County, Ohio, June 16, 2019.
A margined calligrapher,
Toxomerus marginatus, taps nectar from the flower of brookweed,
Samolus parviflorus. The blossom is only 3mm across, giving scale to the elfin flower fly, which is an excellent bee mimic. Shawnee State Forest, Scioto County, Ohio, June 6, 2019.
From afar, this gold-spotted ghost moth,
Sthenopsis pretiosus, would be nearly invisible. It hides in plain sight, looking all the world like a bit of dead leaf. Sharp-eyed Laura Hughes spotted it. The caterpillars of this interesting moth eat ferns. Shawnee State Forest, Scioto County, Ohio, June 6, 2019.
A summer azure,
Celastrina neglecta (L) butts heads with a harvester,
Feniseca tarquinius. The two butterflies were tapping minerals from moist gravelly ground. Each is no larger than a quarter. Shawnee State Forest, Scioto County, Ohio, June 6, 2019.
A northern pearly-eye, Enodia anthedon, regards the photographer from a nearby leaf. I normally find these butterflies tough to shoot. They frequent dim forest understories, and are prone to quickly flushing and then alighting high on a tree trunk, facing downward. Not so this one. It flew right to me as if to demand its photo be taken. Scioto County, Ohio, June 16, 2019.
A pair of six-spotted tiger beetles,
Cicindela sexguttata, making more of their kind. These predatory beetles are the cheetahs of the insect world, chasing down lesser bugs with astonishing speed. Scioto County, Ohio, June 16, 2019.
