I just wanted to add on a little to what Oglemi said.
A ladybug can also be awarded for a combination of the things Oglemi mentioned. For example, a user could have 3-4 analyses, some good rating in the RMT forum, and helpfulness / contribution to discussion in the Smogon Metagames forum and be considered for the badge. Contribution and helpfulness does not go unnoticed, the moderators and admins are always looking for potential contributors. That being said, asking for the badge most certainly will not get you anywhere.
