On Sunday morning with the man-child delivered to a party near my favourite vismig spot I spent a couple of hours seeing if I could record 100 species there. Turned out I could and I'm now contemplating dual-squaring next year. I may not record the high numbers originally intended on my first patch but it might help with variety and it's closer to my work. Also it gives me a better excuse to do some proper vismigging. I think it's probably how that's going to go down. The patches are sufficiently different that it'll be interesting to see what the overall total would be.
Numbers:
| 1365 | coleoptera | Anthobium unicolor | A rove beetle | |
| 1366 | coleoptera | Bembidion guttula | A ground beetle | |
| 1367 | millipede | Nanogona polydesmoides | Eyed Flat-backed Millipede | |
| 1368 | * | fungus | Pseudopeziza trifolii | A fungus |
| 1369 | S | coleoptera | Neuraphes elongatulus | A rove beetle |
| 1370 | * | diptera | Opetia nigra | A fly |

Interesting to see the effect that latitude has on different families - your total of 227 diptera is 62% of my total of 368 - given I'm able to devote more time to collecting/keying, it suggests that the totals in the two squares would be pretty similar with the same effort. But your total of 30 species of hymenoptera is just under 20% of my total of 153. I assume that this difference is real and not an artifact? Suggests that hymenoptera really do like warmer climes. Not sure how to interpret the much higher numbers of fungi, algae, lichens and bryophytes in your square, but I suspect that the converse is true, that your wetter colder climate overall is better for this group, even though some of the difference is due to my being rubbish at IDing these species.
ReplyDeleteI expect the difference is mostly determined by focus, including my relative hopelessness with hymenoptera, many of which i don't attempt. That being said there are undoubtedly less species of hymenoptera. There are less species of flies, too, but there are more than enough! Any idea of the county total for diptera? Ours is relatively poor at just under 1000 but then I can easily add one per month - I'll tally it up shortly now I think about it.
DeleteNo idea about the number of diptera recorded in Norfolk, Ali, but probably quite high I would think given the amount of Broadland fen habitat plus the Brecks and the coastal marshes. There's no easy source for such info as far as I'm aware. Not quite sure how much Norfolk stuff gets onto NBN.
DeleteGood going Ali and also good to see you are planning for next year!
