You would think narrowing down an identification to “shield bug” would have you almost done, wouldn’t you? Man, that doesn’t even narrow it down to family. It was ridiculous trying to get this handsome little guy down from “bug” to “stink bug” (nope) to “soldier bug” (nope) to “shield bug” (nope) to “shieldbacked bug” (at…

Pink-striped Oakworm Moth
This fuzzy little pink-to-orange silk moth of the family Saturniidae is found across Canada and the US. The females are larger (maybe an inch and a half long); the males have large transparent spots on their wings. Both sexes have the little white spot on each wing. In Florida, these guys reproduce year round. Males…
Green Lacewing Eggs
These delicate little white eggs, each on its own half-inch stalk, are about 2mm long. They actually hatch into some fairly fierce predators: the larvae of green lacewings (Chrysopidae). The adult insects are delicate little things (although still predatory) but the half-inch larvae have huge, spiky mandibles and are known as aphid wolves or aphid…
Blue Dasher Dragonfly
Whoever named the blue dasher dragonfly (Pachydiplax longipennis) clearly hadn’t seen a female; this female has almost no blue on her whatever. The males, of course, have bright blue abdomens, a green striped thorax, and green eyes. Blue dashers are “perching” dragonflies; they regulate their body temperature by basking in the sun. If they really…
Root Maggot Fly
This is one of those species where the scientific web sites say almost nothing, other than to argue over semantics and exactly who named the insect last, and the pest control sites have a lot to say. (What can I say, nobody seems to want to write a PhD thesis on small, feces-eating flies.) As…
Ailanthus Webworm Moth
This tiny (1 cm) day-flying moth is actually native to Florida (so it’s funny I found this one in Indiana). The moth’s larvae used to live almost exclusively on the paradise tree (Simarouba glauca) in Florida, but when the “tree of heaven” (Ailanthus altissima) was introduced to the US from China, the ailanthus webworm moth…
Leaf-Footed Bug
This is probably an adult female leaf-footed bug (Acanthocephala declivis) — this species is named for the exaggerated “femurs” on its back legs, and the femurs are larger in the male, with impressive spikes. She’s about an inch and a half long, not including her antennae. Leaf-footed bugs are named after the “leafy” extensions of…
Julia Butterfly
Dryas iulia (often incorrectly spelled julia) is also known as the Julia butterfly, Julia heliconian, the flame, or flambeau. It is the sole member of the genus Dryas, native from Brazil to the southern United States. There are more than 15 described subspecies. Approximately 80-90 mm across, its elongated wings are primarily orange with black…
Black Horse Fly
Anyone who has owned livestock will know this inch-long black fighter jet of a fly. Black horse flies (Tabanus atratus) are huge, loud, and persistent attackers of mammals in the females’ quest to get a blood meal in order to reproduce. They fear no swatter. A million years ago, I worked at a wolf sanctuary,…
Citrus Flatid Planthopper
The citrus flatid planthopper (Metcalfa pruinosa) makes me happy. It is a member of the family Flatidae, whose name amuses me greatly (and, yes, references the fact that these insects are “flat” when viewed from above). Also known as the frosted moth-bug, Pruinosa is common in eastern North America, ranging from Canada to Mexico. Adults…
Eastern Black Swallowtail
This is a newly hatched baby eastern black swallowtail (Papilio polyxenes). It’s only about 6mm long, practically invisible on this plant. By the time it’s ready to become a butterfly, it will have molted four or more times, and will be about four inches long (see photo below)! The white spot on its back is…
Whitefringed Weevil
The whitefringed beetle, or whitefringed weevil, Naupactus leucoloma, is originally from South America but can now be found across the southern US, Australia, and South Africa. They are a type of weevil with a broad, down-pointing snout. Adults are relatively large for a weevil, around 12 mm long. N. peregrinus is light to dark gray-brown…
Dog Day Cicada
Growing up in Kentucky and Indiana, I saw one or two of the big “cycles” of the 17-year cicadas. Those periodical cicadas don’t live in Florida, but here we get serenaded each summer by a variety of annual cicadas which brood every year. The dog day cicada (Tibicen canicularis or Neotibicen canicularis, depending on whom…
Halloween Pennant Dragonfly
I love these dragonflies, because they are so easy to identify — they are the only dragonfly in Florida with those multiple big, brown spots all over their wings. Also, who doesn’t love Halloween?!? Celithemis eponina lives all over the eastern United States, mostly near bodies of water. They mostly appear in the summer in…
Thread-Waisted Wasp
Originally I thought this was some sort of fly. Then I thought it was a wasp. Then I thought it was a wasp mimicking a fly. /r/insects didn’t know what it was. Months later, while searching for Polistes wasps on google, I scrolled past a picture of a similar species of sand-digger wasp, and —…
Paper Wasp
Paper wasps (Polistes sp.) are named because of the paper-like nests the queens build. They are members of the family Vespidae. Paper wasps are primitively eusocial, like bees. There are three castes: fertile queens, infertile female workers, and fertile males who do nothing but fertilize the queen. Founding queens sometimes start a nest in a…
