I am particularly interested in your aphid control because I think my 
Drosera's currently have an aphid infestation.  It's also moving onto 
the U. longifolia.  I'm looking at tiny whitish-yellow 'dandruff' on the 
flower scapes and leaf petioles, and they don't move.  They must be 
aphids, even though they aren't the fat, fleshy looking things I 
recognize.  (Augh!  See what will happen when you neglect them 
during one of those intense 5 week winter session courses!)
Did you try immersing the D. capensis in a bucket of water for a few 
days?  Did it work?  I was going to try this approach this weekend.  
Can someone dig out the soap/oil mixture in water recipe or suggest 
other methods of control?
