Teneral cicadas

I started annotating large numbers of teneral cicadas as such. To do this for a given observation, I go to an observation and then under "Observation fields," I type "teneral." It gives you the option of selecting "Yes," "No," or "Maybe." I alway select yes, since I'm doing this only for tenerals. I then push "Add" and it's done. After the first time, "teneral" shows up in the "Observation fields" menu, so you won't have to type it.

So far the number of cicadas annotated as teneral number 1254. I have focused on the southeastern and central U.S. so far. You can see them here: https://www.inaturalist.org/observations?place_id=97394&taxon_id=50190&field:teneral=yes . Note the "&field:teneral=yes" part of the URL. This can be added to any explore or identify URL to restrict the observations to tenerals.

What is the value of such annotations? It will help us better understand how to identify them as they are more difficult to identify than fully hardened specimens. One can browse given species, to develop a feel for the appearance of their tenerals. For example, here are all the teneral Neotibicen superbus, via identify:


To look at the tenerals for a given species, simply go to identify and select the species of interest, under Filters, toggle on "Research grade" and "needs Id" and select Reviewed as "any" and push "Update search." The add "&field:teneral=yes" to the URL and hit the return key. You can then browse as many as you like.

Unfortunately the current state of affairs is that a lot of tenerals are misidentified, so keep that in mind as you browse. I like to pay particular attention to those identified by @billreynolds, @rlsanders, @easmeds and @willc-t four experts on US cicadas. Those identified only by others are very likely to be misidentified.

I encourage @willc-t and @easmeds and others to annotate any tenerals they see.
