Hi Folks,
I know you know what I'm talking about.  It often infests the 
undersides of the fronds.  I thought I ID'd it as Idiopteris 
nephrelepidis, but I'm not 100% positive.
It also looks a lot like Aphis gossypii in its black form.
Can anyone help?  I can use soap and oil, and I'm using some 
parasitic wasps, but I'd sure like to know what it is.  I guess I'd 
better send it off to be ID'd.
Thanks,
Shelley
