When the bike is at high speeds. The bike requires more energy to propel the bike so, it draws more fuel into the system.
Think about how the internal combustion engine works. In order to make the pistons move it requires the intake of fuel, the compression of the fuel, and then the combustion of that fuel followed by the exhaustion of the waste. (hence the 4 cycle engine) The faster you want to go, the more times you need this cycle to repeat itself. Ergo, the more fuel you will need. Depending on the bike, you may be idling at around 1,000 RPM's or so. Now think about how many RPM's you are pushing at high speeds. Anywhere over 9,000. So it will need to draw a lot more fuel into the system.
At idle speeds it is drawing enough fuel to keep the engine running. Although if your idle speed and high speed are the same RPM's.... then the fuel required is the same.
Think about it his way, do you burn more calories (body fuel) sitting on the couch playing Madden '07on the PS3, or, outside playing a game of real football?

Riding at high speeds, you're consuming more fuel per second, than if you were just idling the engine at a stop light.
Why - the bike is reving faster and burning fuel faster.
But if you're riding at low RPMs (say under 6,000) in high gear, then the gas mileage will be better than just idling.
Why - say you were moving at 60 mph. Gas consumption rates between idle and 6,000 rpm is minimal. But since you were moving, after an hour, you traveled 60 miles, as opposed to zero, just sitting there.

You consume more fuel at high speeds because the faster your engine goes the more fuel you consume. We have different gears in the transmission so our engine does not go too fast. So the one guy was right when saying RPMs are the determining factor.
But going is faster is still more efficient than not going at all. If you are getting 40mpg while going fast, you are still getting 0mpg while not going at all. So if you are talking about per distance, not moving is less efficient.

It would actually consume the most fuel at high RPM rather than high speed, this is because the number of ignitions is really the determining factor.
That is to say, you will consume more fuel at 6000 rpm at 20 mph in 1st than you would at 3000rpm at 75 in 5th or 6th.

At higher speeds, the more fuel you consume.

I'll assume you are speaking of a motorcycle. While it is at high speed, more fuel is consumed bythe motorcycles engine because the engine is turning more revoloutions per minute. Therefor the engine is displacing more air and fuel.

speed has nothing to do with fuel consumption, rpm have everything to do with fuel consumption. if you were sat at a red light revving the bike up to 10,000 rpm, you'd be using an awful lot of fuel.

are you kidding? what takes more energy, holding an idle engine at a stoplight or overcoming wind resistance and frictional losses plus velocity at speed? the key to your question though is that at rest you are getting 0 miles per gallon so even though you are using more gas at speed it is still more efficient than being stopped...

when it is at high speeds of course, as the further you open the throttle so the fuel intake increases.

the faster you go the more hp it takes to over come increasing air resistance, generating more hp takes more fuel . the same as a car or truck
