Question : regex move command in Ubuntu, how would I move the following files to a directory?

I have a directory of 10,000 files... with the same naming schema..

bigapple_lrg.jpg
bigapple_01_lrg.jpg
bigapple_02_lrg.jpg
bigapple_03_lrg.jpg
bigapple_04_lrg.jpg
bigapple_05_lrg.jpg

banana_lrg.jpg
banana_01_lrg.jpg
banana_02_lrg.jpg
banana_03_lrg.jpg
banana_04_lrg.jpg
banana_05_lrg.jpg
banana_06_lrg.jpg
banana_07_lrg.jpg
banana_08_lrg.jpg
(some items go up to _60_lrg.jpg)
etc..

I want to move all the files with "_##_lrg.jpg" to a sub directory "/extrapics" , but leave files like "banana_lrg.jpg" in their current directory.

Is there some kind of regex way to move the files like:

mv *_\d\d_lrg.jpg /home/myself/documents/website/extrapics/

This should do it I believe - test it first on something that doesn't matter though!

mv *_??_lrg.jpg /home/myself/documents/website/extrapics/
