It might be useful to display the bee names that are being matched with the feeds to give some indication of why a particular article is appearing on the list when it might appear to not be related to bees.

The uBioRSS feeds display HTML instead of it being correctly parsed. My opinion is that this is a drupal issue. Example:

Effects of azadirachtin on mortality rate and reproductive system of the grasshopper Heteracris littoralis Ramb. (Orthoptera: Acrididae)

It appears to not catch the EM tag.
