For anyone following the Casey Anthony trial?

So the Entomologist that came up today, I heard somewhere that he was taught by the prosecutions Entomologist? Kind of like a student and the Pros. Entomologist was the teacher. Is this true? Also, I heard all that this entomologist had to say today about the trunk, stain, bugs and how there is really no evidence judging by photographs.. and I hear from people.. in comparison to the pros. entomologist, he pales in comparison? I am just wondering what exactly the pros. Entomologist had said in his testimony that pretty much cancels this dude out and makes him look like a fool. Cause I actually missed that testimony.
