Wasp and Cicada Together

Earlier this month, a wasp and cicada caught our eyes. I might have whipped out my measuring stick and laid it near the duo, but decided to not disturb the wasp. As it turns out, several resources claim that the wasp is likely busy and not interested in a nearby human. From Cicada Mania's "10 Facts about Cicada Killer Wasps"
They are so focused on cicadas or other Cicada Killer Wasps, that they could care less about you. Sure, if you step on one, squeeze one in your hand, or otherwise harass the insect, it might sting you. Unlike other wasps, it will not go out of its way to harm you. Play it safe, do not go near these wasps, …
The last few months have been interesting for encountering cicadas and related items—exuviae (discarded exoskeleton), cicada wasp (humongous insect), and a molting cicada visitor on my doorstep—all separate events. This incident was different—both wasp and cicada in the same scene. In looking closer at the pictures and doing Google lookups, a real oddity was the size of the pictured wasp compared to the cicada. Resources such as Cicada Mania and BugGuide.Net describe the wasps as large.
If you compare the pictures with numerous online images or videos of wasps flying with their prey, my wasp is an absolute peewee. As I didn't spend much time with the duo, and didn't shoot a video, I'm inferring a story. The cicada's back faces the sky. For the wasp to use the cicada as food source for its larva, it must be able to insert the egg into the cicada. In the three pix, the wasp looks waaaay too small to be able to turn the cicada onto its back.


Walking in the same area the next day, did not see either insect. Dang! Missed opportunity.

While researching sites and videos to better identify the wasp and cicada. I noted a couple of coincidences:
Additional video resources show wasps with cicadas. Those wasps are maybe half the size of the cicadas (unlike peewee wasp), but strong enough to haul their prey. Some of the videos also include narration about the wasps' actions on the hapless cicadas.

Molting Cicada Visitor at My Doorstep



Last month, on my way back from a morning walk around 8 AM, I spied a cicada partially emergent from its exoskeleton at my front door. It looked to be trapped and unable to have exited. Took pix, natch. Checked later, and found it had moved. In the course of the day (about 4 1/2 hours), the two of us took series of pix and videos. (View the finished YouTube video.)

Around mid-day, the other pictaker took a last shot of the cicada, fully extended, still drying out. Shortly thereafter, we saw it had departed, leaving the exuviae that had a more slender exit cavity than I'd seen of other vacated shells. The video is time-sequenced for cropped stills and clips. Most amazing is capturing stages of emergence and the stunning mask-like look on its back.

Note: Somehow, I missed the shelly cicada on my way out for my walk (7-ish, maybe). I either didn't spot it, or it approached the doorstep during my walk. View "Cicada Molting - Nature Time Lapse (Cicala fa la muta)" to see a couple of shelly cicadas undulating and splitting the shell backs, starting the emerging process, then completing the molting process.

Bugguide.net and Cicada Mania
Bugguide.net has been my most frequent go-to site for bugs. For this article about cicadas, Cicada Mania's "The most interesting 17 year cicada facts" bubbled to the surface as a compelling site to visit.
More worthy Cicada Mania sites:
Some images from Bugguide.net's "Subfamily Cicadinae" page resemble my visitor cicada. The genus might be neotibicen ("Genus Neotibicen - Annual or Dogday Cicadas") or megatibicen ("Genus Megatibicen").
From "Genus Megatibicen"
Identification
Most members of the Megatibicen are >2.5 inches long (incl. wings). Megatibicen are often "stockier in appearance" & characteristically more pruinose (white powdery wax) than are most members of the Genus Neotibicen.
Pee Ew
One of the clips in my YouTube video shows the emergent cicada spraying a fluid. Did it pee? Sure looked like it did! Found some info and a video, although these cicadas were already free of their shells.

At Massachusetts Cicadas site (slogan: Dedicated to the Study of the Cicadas of Massachusetts and New England), "Cicada Molting/Eclosing Process" shows a timeline a timeline of the cicada's emergence. For ick factor, view the closeup of cicada pee. Cicada Mania's "Do cicadas pee?" mentions cicadas after they molt, not during. The site includes YouTube video "Cicadas - Drinking & Peeing (01Apr2012a)" of branch with emerged cicadas on it spraying away. (The spray resembles the emission as from my molting cicada visitor.)
