Bug hunt!

A break from college work to go look for some bugs in the garden :)

Really needing to look into some new lenses.
I know photographers really hate it when people say this as i found out when asking on a "photography help website", resulting in a tonne of abuse from one guy...no need pal everyone has to start some where right??

But seriously can anyone recommend a good, decent priced zoom lens and macro lens to help me out a bit?
