We all want to know "What the heck izzit?" and sometimes we can find out from pics on the net or elsewhere.
The biggest Q in the long run becomes, though, I think, "Are the darn things all gone yet?"
It's a battle. It helps to know the enemy to some extent for sure, but sometimes just miscellaneous firing on them with the standard herbicides & zapper will kill them whether you knew what they were or not.
