A Call to Grass

Hi everyone,

I stumbled over this observation https://www.inaturalist.org/observations/28990168 of Cynosurus cristatus yesterday, which @bobwardell helped to identify. In checking the stats on the taxa page https://www.inaturalist.org/taxa/76581-Cynosurus-cristatus I found that we have only 12 observations in Germany so far, though wikipedia says it is a quite common grass, though locally listed as endangered. But looking at the GBIF data points in the map, it seems it should not be so difficult to get some more observations of it at iNat, though it seems to be advantageous to explore in Bavaria.

Digging a bit further in Poaceae it seems that many grass species are way too overlooked in general.

Poaceae observations in Germany: ~ 3000 observations with 161 different species sounds maybe not to bad. But a big chunk of them are not surprisingly Phragmites australis (266) and some others, and many, I assume, unidentified deeper than Poaceae:
https://www.inaturalist.org/observations?locale=de&place_id=7207&preferred_place_id=7207&subview=grid&taxon_id=47434&view=species

So I would like to give a Call to Grass for some of them (completely arbitrarily chosen ;-), their visuals seem catchy enough to remember them), which hopefully raises other Poaceae observation counters as well.
- Crested Dogstail (Wiesen-Kammgras), https://www.inaturalist.org/taxa/76581-Cynosurus-cristatus, currently 12 observations
- European Feather-grass (Echtes Federgras), https://www.inaturalist.org/taxa/355674-Stipa-pennata, currently 2 observations
- King Ranch bluestem (Finger-Bartgras), https://www.inaturalist.org/taxa/75842-Bothriochloa-ischaemum, currently 2 observations
- Blue Moor-grass (Kalk-Blaugras), https://www.inaturalist.org/taxa/363774-Sesleria-caerulea, currently 4 observations
- Giant Fescue (Riesen-Schwingel), https://www.inaturalist.org/taxa/162949-Festuca-gigantea, currently 11 observations
- Wood Millet (Waldhirse), https://www.inaturalist.org/taxa/165390-Milium-effusum, currently 18 observations

Any additions to the list, especially from a more expert point of view, are welcome!

Happy exploring!
Monika

Say hello to the targeted species

(This blog entry is just in order to loosely collect/link all surrounding information that was given in comments or other journal posts of this project in one source)

Insects // Insekten

https://www.inaturalist.org/taxa/48612-Myrmecophilus-acervorum

https://www.inaturalist.org/taxa/624530-Pionosomus-varius

https://www.inaturalist.org/taxa/329849-Drosophila-simulans
-> https://www.inaturalist.org/projects/inat-challenge-germany/journal/27878-new-target-species

https://www.inaturalist.org/taxa/430143-Boreus-hyemalis
Informations about it (in german): https://www.insekten-sachsen.de/Pages/TaxonomyBrowser.aspx?id=223691
Can be found:
- on mosses: Hylocomium splendens, Pleurozium schreberi, Hedwigia albicans, Polytrichum piliferum and Grimmia sp.
- from October til March

https://www.inaturalist.org/taxa/52506-Adalia-bipunctata

https://www.inaturalist.org/taxa/865359-Phloiophilus-edwardsii
- not too hard to identify due to its distinctive pattern
- However, it is only active in the winter season around oak trees and quite small, which could be the reason for the poor reporting

https://www.inaturalist.org/taxa/202770-Eresus-kollari

https://www.inaturalist.org/taxa/1038184-Cacopsylla-crataegi
- can be found on murals and crataegus and other places

https://www.inaturalist.org/taxa/882693-Cheilosia-fasciata
- german name "Bärlauch-Erzschwebfliege" and only 5 records in germany, while there is so much Allium ursinum everywhere!
- similar species: https://www.inaturalist.org/taxa/334407-Platycheirus-albimanus, https://www.inaturalist.org/taxa/486669-Platycheirus-discimanus, https://www.inaturalist.org/taxa/486775-Portevinia-maculata (red antennae), https://www.inaturalist.org/taxa/486771-Cheilosia-semifasciata (not as distinctive spots, light hairs on the eyes; among other traits)

Mosses // Moose
https://www.inaturalist.org/taxa/156527-Pottia (which now belongs to Tortula, see https://www.inaturalist.org/taxon_changes/68776, but anyway)
- lives very short time and is very tiny
- only 3 iNat records so far
- how does it look like? Check out this obs by alexis_orion: https://www.inaturalist.org/observations/37188499
- it is now part of Tortula (https://www.inaturalist.org/taxon_changes/68776)
