Lepidostoma (Little Brown Sedges) Little Brown Sedge Larva

Hexatoma True Fly Larva

View 6 PicturesI'm not sure if this cranefly larva is in the genus Hexatoma or Limnophila, but the habitat suggests Hexatoma. Its coloring is iridescent, and I've never heard of that before. However, there is an insect virus genus Iridovirus which can infect craneflies and causes iridescence. It has not been reported in this region as far as I can tell, but perhaps it is the culprit. It makes for beautiful pictures.

Tallaperla (Roachflies) Stonefly Nymph

View 6 PicturesThis is the first specimen of the Peltoperlidae stonefly family that I've collected. It's very small and probably an early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.), but I'm not choosy about new bugs.

Ephemerella aurivillii Mayfly Nymph

View 6 PicturesThis specimen was collected together with a lighter one of the same species.

It resembles another specimen from about 1300 miles away in Wisconsin, which I tentatively called Ephemerella needhami. This one has much less prominent abdominal tubercles (

A few (not all) of the abdominal tubercles on this Ephemerella needhami nymph are circled. They are especially large in this species.

Tubercle: Various peculiar little bumps or projections on an insect. Their character is important for the identification of many kinds of insects, such as the nymphs of Ephemerellidae mayflies.). It may be that they're both the same species and I don't have my identifications straight.

Male Siphloplecton basale (Pseudo-Gray Drake) Mayfly Spinner

View 6 PicturesI went to great comical lengths to swipe this spinner from the air with a little aquarium net I carry with me while I'm fishing. Siphloplecton basale spinners fly fast and high over the riffles, and there are never very many of them, so they're difficult to catch.

Jargon Defined:

Abdomen: The rear and usually the longest (ten-segmented in mayflies) portion of an insect's body, to which the tails are attached.

Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.

Larva: Many classes of aquatic insects, such as caddisflies, midges, craneflies, dobsonflies, alderflies, and many more, are known as "larvae" rather than "nymphs" in their juvenile stages. They have mostly soft bodies rather than hard exoskeletons. These insects also advance through a "pupa" stage before reaching adulthood.

Spinner: There are two winged stages of adult mayflies. They emerge from the water as duns, molt on land (usually) into their fully mature stage, spinners. As spinners, they mate, lay eggs, and die.

A few (not all) of the abdominal tubercles on this Ephemerella needhami nymph are circled. They are especially large in this species.

Tubercles: Various peculiar little bumps or projections on an insect. Their character is important for the identification of many kinds of insects, such as the nymphs of Ephemerellidae mayflies.
