Hi,
I think you need input here from Gareth, he's the only one of us with
experience broad enough to have encountered nosema.
What I can say is: bee poo is yellow. What these white dots look like is wax.
Let me go check inside my own windows... right, I can report that my windows do
not have these white speckles. What they do have, in some areas, are areas
where wax used to be attached to the windows, which look like yellowish smears
or dots or streaks:
...That's because I re-use boxes after harvesting them, or cleaning out a
deadout, and I find it difficult to clean all traces of wax / propolis from a
box or window. I suppose I could blowtorch them, which is meant to be better
for sterilising, but I like them to retain some bee-smells to attract swarms.
Those streaks of old, hard wax tinged with propolis tend to be yellow.

Dear friends,
This is on the window of one of my hIves.
In my haste to hive them last year as a wild storm was about to break, I
omitted putting in top bars . They rapidly went on to fill the hive with
wonderful wild comb and they have pulled through so far. Does this look like
Nosema on the windows?
No streaks. Advice appreciated as always.

The first OxNatBees meeting of the year will be at the [Marsh Harrier
pub](http://www.marshharriercowley.co.uk/) in Cowley, Oxford on Saturday,
March 10th.
Start time: 1PM. The pub serves food.
The following discussion topics have been suggested but of course, all
questions are welcome:
- winter survival
- immediate tasks (remove mouseguards, how to check colony health etc)
- what we are planning / preparing this year
- how to repair hives with bees in residence
- the imminent swarm season
The pub is within walking distance of Jack's top bar hives and if weather
permits, at the end of the meeting we will go and look at them. One hive has
an emergency rescue colony in it which Jack does not expect to survive: if
it has died we will open it up and show how to do a post mortem on it.
We will be joined by someone who wishes to promote the [Bee.Watch
app](http://www.bee.watch/), they are based in south Oxfordshire and after
having several hive losses from spray poisoning they have written the app
and are promoting it to various bee groups.
