We had a short Neotibicen cicada season in New Jersey in 2022.
I’m used to finding molting Neotibicen cicadas between the first week of July and the last week of August. This year they started emerging in the first week of July, but the last one I found was on August 2nd.
I wonder if the short season was due to the major drought or heat waves New Jersey experienced this summer.
Here are some photos of a freshly-molted/teneral(soft) Morning cicada:

Neotibicen tibicen tibicen (Linnaeus, 1758) aka Swamp Cicada or Morning Cicada. Morning because it sings in the morning. There is another sub-species of Neotibicen tibicen names Neotibicen tibicen australis. The key difference between the two is australis has a mostly green collar, while tibicen’s collar is black.
Description: Swamp Cicadas are are known for their rounded, humped back. Their coloration varies from mostly black & some green to black, brown and green. Their collar is usually black, but can include green.
This is France’s Walker’s description from List of the specimens of homopterous insects in the collection of the British Museum, Francis Walker, edited by John Edward Gray, Supplement, (2 p. l., 369,  p.) issued in 1858, 1850. Link to document.
Walker named the cicada Thopha chloromera, and once the Tibicen genus was constructed, its name changed to Tibicen chloromerus (Walker,1850). But… Carl Linneaus had previously named it Cicada tibicen in 1758, and once the Neotibicen genus was constructed, its name became Neotibicen tibicen (Linnaeus, 1758).
That said, Walker’s description is still valid and useful:
First cross-vein nearly straight, very slanting, forming an extremely obtuse angle, parted from the second by more than thrice its length; second curved, very slanting, forming an extremely obtuse angle, longer than the first; third slightly waved, slanting, forming a right angle; fourth slightly waved, slanting, forming an acute angle, a little longer than the third; fifth almost upright, very slightly curved, forming- a nearly right angle. Body black above, tawny and tinged with green beneath : head a little narrower than the fore-chest, adorned with several small tawny marks, and on each side of the front with one of larger size ; face slightly convex, not at all prominent, adorned with a pale tawny elliptical mark, tawny with blackish bands on each side in front : mouth tawny with a pitchy tip, reaching the middle-hips : eyes rather prominent : scutcheon of the fore-chest adorned with two oblique black stripes, which are united behind; fore border black excepting a little interval in the middle ; hind-scutcheon adorned on each side with three greenish- tawny spots, one large, the other two small ; sides not angular, but slightly excavated in front and slightly convex near the base of each fore-wing : scutcheon of the middle-chest adorned with a tawny slender double U-shaped mark whose inner sides are interrupted in front and behind ; on each side of this are two oblique tawny stripes which are united behind ; the middle pair are broader than the outer pair, and their inner sides are excavated ; hind border slightly excavated in the middle ; cross-ridge tawny : abdomen obconical, longer than the chest, black above, tawny beneath : drums very large, pale tawny, much more than half the length of the abdomen, slightly overlapping : legs green, streaked with tawny; fore-thighs armed with two stout black teeth ; spines of the hind-shanks ferruginous with black tips : wings colourless, bright green at the base ; veins ferruginous, green towards the base and along half the length of the fore border ; first and second cross-veins clouded with brown.
