What is chirping in the St. Petersburg park?

Community and Forum → Insects biology and faunistics → What is chirping in the St. Petersburg park?

That's a mystery, isn't it?.. Last year, in a nearby square near the house, I heard for the first time one singer, this year there are already at least several of them. There is no directional microphone, no way to catch it. I walk around the tree, like the famous heroine of Krylov's fable around grapes, and lick my lips.

In general, starting at about 10 pm, trills lasting from several seconds or more are carried from the oaks in the square. The chirping sounds are vaguely reminiscent of Tettigonia cantans songs, but something more "dry" - and the cantans at this time of day would not be shouting for tens of seconds, but for many minutes in a row. In general, someone else. Did Tettigonia caudata really start up in St. Petersburg? I haven't heard this grasshopper in 20 years, so I might have forgotten the song. Or maybe even a mountain cicada?

The address of the mysterious square is St. Petersburg, Novocherkasskaya metro station, between Novocherkasskiy Prospekt and Shaumyan Avenue, insects themselves sit on trees along Republikskaya Street-this is if any of the residents of St. Petersburg decide to record the signal smile.gif

Well, who is sitting in the trees so vociferous? Couldn't catch/write? Gampsocleis sedakovii polaris ssp. n., ali Parachyphoderris erebeus wink.gif

I didn't write it down then. I look forward to next summer. The choice, of course, is more modest. Either T. cantans was not recognized against the background of city noise, or - which is extremely unlikely, but I really want to-T. caudata was brought with the soil during the reconstruction of the park.

Can you learn more about Gampsocleis sedakovii polaris? Is this a joke, or did someone support the findings of G. sedakovii in the forest tundra of Western Siberia with collections and descriptions? Because photos from there were posted on this forum.

Tettigonia caudata is very fond of singing in the afternoon, in the evening. It's strange that it's after 10 pm. How was it this year, I wonder, did you check it out?)

Well, wow!! I live on Piskarevka Street (in Saint Petersburg) I've never heard
a chirp in my area, and I've never seen Tettigonia sp., just hortippus.

In fact, there are a lot of people in the city - and even a few years ago... There are at least 3 types of grasshoppers in the city limits alone. And this year I still don't know if there are any grasshoppers left on Okhta - I returned to the city recently, and the weather is bad.

Do you have cicadas of the genus Cicadetta live there? As a child, I also thought that a grasshopper had climbed into the crown, until I dared to look for a songbird.

Cicadetta montana is known from the vicinity of St. Petersburg, but only locally - on the Duderhof heights. This year, their exuviae were collected there by colleagues in early summer. Where it came from there is another question. Either it is a relic of the Holocene optimum, or an introduced one (under Catherine II, trees from the Carpathians were planted there). But it is very far from Okhta to Duderhof.
