When a fly lands on your food it firstly tastes the food with sense organs in its feet. When it realises it is good to eat it then 'vomits' digetive fluid onto the food which turns it into a liquid 'soup' (on a small scale of course - this is only a tiny area but it is enough for the fly). The fly then mops it up using its modified proboscis (elongated mouthparts) which is shaped like a sponge at the end. And they tend to judge us based on our personalities!
When a fly lands on a surface it will regurgitate to get rid of the food that it has previously been on which could be anything from faecal matter to rotten flesh.
If a blow fly lands on food it will most likely deposit an egg. The eggs will hatch maggots which will eat the food and it will go rotten.
The fly does, so when it lands on food, it can see if it wants to eat what it is on.
When a fly lands on you, it may be looking for food, warmth, or shelter. It may also be attracted to any scent or moisture on your skin. If you try to swat it away, the fly may quickly fly off and find another spot to land.
No it does not.

The " mouth" of the Venus fly trap is covered in a very sticky sugar substance. Flies love sugar. When a fly lands on the sugar in the Venus fly traps' mouth, it gets stuck. Then the Venus fly trap closes it's mouth and digests the fly.

Not Always, Sometimes They Will.
its a real fly!
A fly does not defecate every time it lands but it is not uncommon for them to do so. They do not specifically defecate at certain times or in one place like many insects.
Because they find there food in tropical lands...
