Annual Cicada (Neotibicen spp.)

Terrestrial, hatching July–August, active in water between 60 and 78°F, and imitated at #6–10. Recorded from the North Carolina mountains, where 1575 North Carolina rivers on this site carry a page.

What it is

Terrestrial · Neotibicen spp. · adult

Larger and duller than the periodical species: green-and-black or brown body, clear wings, dark eyes. The insect responsible for the sound of an August afternoon.

The cicadas heard every summer, and unlike the periodical broods they turn up every year. Never in emergence-year numbers, but a river with wooded banks puts enough of them on the water in August to be worth a big foam fly on a hot afternoon.

When it hatches

Peak is July–August. The pale months either side are the shoulder — the app widens a peak by one month in each direction and recommends the bug there, and no further: that widening is bounded so that a bug peaking in May is never offered in August.

Water conditions

The band is a water temperature, not an air temperature, and it is the range in which this insect is worth fishing — for a mayfly that is the emergence window; for a scud or a midge it is simply the range trout will still eat one in.

60°F 78°F

Active from 60°F to 78°F. On this map that is cold-transitional, cool, warm water — the band crosses 2 of the three breaks the river colours use. Breaks at 58, 64 and 70°F.

Stages

What the insect is doing, and what that means for what you tie on.

Stage	What it is
adult	Turns up every summer rather than once a generation, and never in brood numbers. On a river with wooded banks, enough of them fall in through July and August to make a big foam fly worth carrying on a hot afternoon.

Matching flies

3 patterns in this book imitate the Annual Cicada, across its stages. Which one to tie on follows the stage the water temperature says it is in — the app makes that call on a live reading; this page lists the whole set.

Where to find it right now

The rivers with a page here that sit in this insect's regions, with a USGS gauge reporting water temperature. This list is re-ranked against the reading each gauge is sending now and today's date, so it is live — the fallback below it, if the readings do not arrive, is each river's measured July mean.
