Still can't start much reading here (let alone revision): always more pressing things to do against deadlines. Depressing. I really, really don't want to have to wait 20 months or so to resit!!

page 36 Gould and Gould Grant
"Workers die after nine days of heavy foraging, or up to three weeks of light-duty collection. The flight muscles simply wear out after about 800 kilometres, usually when the forager is en route to food or on the way back."

What are your sources?

Sending you all positive vibes... I'm feeling the pressure too.

Do the numbers make any sense? 800 Km over 9 days is somewhere over 70Km a day. A bee flies at, what?, top speed 20 Km/hour in round numbers. That's 3 and a half hours a day, entirely possible in June when there's 18 or so daylight hours a day. A bee foraging for the usually quoted three weeks could do 800 Km flying less than 2 hours per day. Another way to think of that would be three return trips a day to a source 5 Km away - plus short hops actually foraging.

I can't say what any of the original claims have to back them up but 800 Km seems a lot more likely than 80 Km which a forager would do in 12 minutes a day. 2Km would be a maximum daily range, and we know they do more than that.

Not entirely sure why distance is used, however. It could be related to how far away food sources can be in practice, but with wind speed close to flying time that's going to have a big impact. It would make more sense in assessing wear to use hours flying time, it's what any aircraft engine or airframe uses to set design life and service intervals.

I went on line to look for the source research because I am bored of the books. There a a journal Behavioural Ecology that is free online and has quite a lot about honeybee behaviour in it useful for this module.

I'm not sure that surfing counts as revision though.

There are a LOT of typos in the number stuff for modules. Drives me nuts.
