Workers unite!

Unlike the last two century thresholds this one hasn't suffered from an approaching crawl. A nice diversion, the kind that you need to keep momentum up, has been provided with the arrival of new literature and some wasps. Variety isn't only the spice of life but the spice of the 1k challenge! This book was recommended to me on the BWARS facebook page and I'm happy to pass on the recommendation. I long feared that wasps were a group for another time, but it seems there's a small bite you can take out of them without things getting too deep.


I also continue to reach for Steven Falk's new Bee book, though I still can't say I'm entirely enamoured with them as a group. Much more so than I was a year ago though. My hymenopteran list is already three times what I predicted at the start of the challenge.

Honeybee - where from I wonder?

Crossocerus annulipes

All that leaves me just shy of 900 with the possibility/likelihood that I'll pass it this lunchtime/afternoon. After 8 months and 24 days I finally saw my first Rook this morning. I long believed that Rooks may be moving south in autumn (should check the migration atlas I suppose!). It was hard to be sure as sometimes I saw more north-easterly movements in the evening. However one south over the river today was genuinely the first one I've seen in the square despite there being a nearby rookery. I'll be keeping an eye on them.

Another positive from this week has been an increase in hoverfly diversity. I didn't see many Syritta pipiens last year after their being everywhere the year before. Nice to add one to the list for this patch. Look at that spiny femora!
