Re: Invert. database... what important inclusions?

Does anyone else here wish to tell us about their databases? I think it's pretty interesting - I have entered about 90 insects so far - some of course only to species-level - and among that, 16 Cicadellidae members. Now, I have been recording them from my garden and four other sites. Interestingly, I have only recorded one from more than a single site - that being Zygina flammigera from two localities. The other 15 have been seen in all five sites, just not apparent so far in more than the one I find them in.

Now, with under-recording being a big factor I'm sure I've missed them, but little things like this have the potential to show trends when put down in a table like this, don't you think - points you may over-look when simply recalling from memory?

One other interesting point; you know the green spider Nigma walckenaeri - the one with a very local distribution and classed as a Notable Na species? Well... I've found it present on 4/5 sites!! This makes me think that this one that is probably the rarest across the UK in my area, is perhaps one of the more common here.
