Lime Time

I've been waiting for the Small Leaved Lime Tree, Tilia Cordata, to flower. The time is near.

Not to be confused with the citrus trees which bear Lime fruits, this attractive tree is a big producer of nectar and it's common around Oxford. There are several large mature trees on Parks Road and South Parks road. There are many more around the city and in Headington

Same news from the hive floor

Submitted by will on Mon, 06/05/2017 - 07:41

I had a look at the hive floors in the out-apiary this morning. In the order which I looked at them:

Hive G: lots more comb built. Small numbers of dropped Varroa.

Hive F: lots more comb built. Large numbers of dropped Varroa.

Hive D: lots of activity - evidence suggesting a large number of emerged brood. Large numbers of dropped Varroa.

Hive E: quieter than C and D. Some evidence of brood emerging

Hive C: lots of activity - evidence suggesting a large number of emerged brood. Relatively small numbers of dropped Varroa.

Deformed Wing Virus appears to be seasonal in Hive A

For at least the last 2 years I have observed a definite pattern in Hive A. In spring there are lots of crawling bees outside the hive. Some are clearly affected by Deformed Wing Virus (DWV); others maybe by another paralysis virus or by exhaustion.

They crawl around near the hive. If you launch them into the air they fall back to earth. They never make it back to the hive and have probably been ejected by the other bees. The Sparrows eat some of them. The others presumably die out of site.
