What the Bleep is This?

So, God, I guess you decided that sending me Rose Rosette Disease and wiping out all my modern roses wasn't enough of a trial for me, huh?  A devastating hail wasn't enough?  You didn't remember that your previous gift of Japanese Beetles was surely enough of a plague to throw at me?  You had to find some new pestilence to give me a new challenge?

I was peacefully inspecting the roses on Friday night during a break in the continual storms of the past week, when the skeletonized leaves of the photo above caught my eye.  Gads, I thought, what is this?  Luckily for me, I've been around the rose block, so to speak, and knew immediately what I was looking at; Endelomyia aethiops, better known as the Roseslug.  Or, in it's adult form, a sawfly.   And, as I looked closer, these were on almost every non-Hybrid Rugosa rose in my garden; in other words, on almost all the old garden roses and other hybrids that survived my RRD epidemic.  I've seen them before at the K-State Gardens and in other rose gardens, but rarely in mine and never on some many roses at once.

Of course, I'm not an expert at insect larvae identification, and it could be that these are Allantus cinctus, the Curled Rose Sawfly, or perhaps Cladius difformis, the Bristly Rose Slug.  Still, "my" larvae do not have bristles, nor do they curl up when disturbed, so I'm going to maintain these are Endelomyia aethiops.  Even though I don't really care about the actual identification other than the scientific curiosity of the thing.  I simply want them dead.  I want all of them dead.

Internet sources suggested they can be controlled by handpicking.  Sure, you bet, I'm going to handpick these off of all the dozens of roses out there in the garden. Not!  I also read that they can be removed by spraying with water since they can't climb back onto the plant after they have been dislodged.  And yes, insecticidal soap and horticultural oils are also effective treatments.

Geminy, what a bunch of W.E.E. wimps these internet insect gurus are!  I don't want to just inconvenience these slugs, I want to nuke them off the planet!  I agree with the suggestion of Sigourney Weaver's character (Lt. Ripley) in Aliens; another story about a rapidly breeding destructive set of insects.  "Nuke them from orbit," Ripley said, "it's the only way to be sure."  So I went for the big guns.   Because some of these roses also had a little early blackspot after all the rain, I dusted off my trusty bottle of Ortho 3-in-1 insecticide-fungicide-miticide and went nuclear on these helpless larvae.  You can see the dampness of the spray on the leaves of the second photo.

  

I won't try to defend my actions, except to firmly avow that I carefully followed the label directions. On the contrary, I admit that I enjoyed every second of this momentary lapse from my best attempts to garden organically.  Heck, what good is science anyway, if we can't use it?
