Vicky, you never said what type of camera you have and don't seem to have posted anything for us to find out, but in case you do not have all the DSLR lenses, can assure you that with the hints about how and when and a little patience, you can get very close to some insects some of the time.

With close up rings on a compact close up can be 10-25mm. Admittedly I am more usually after flowers including very small wild ones, but 80% turn out to have an insect in/on as a bonus.
