What is this bug infesting my Homalomena Emerald Green? (Pics)

mommachickadeeOctober 20, 2009

Ugh, this plant is giving me such grief! All I've read about it has turned out to be the complete opposite from my experience. It's supposedly pest-free or close to it, yet this plant has gone through more pest issues than any other plant in my house. And now THIS bug, which I haven't a clue to what it could be. I've tried looking it up, but to no avail. Anyone know? And if so, could you kindly help me to rid this plant of them? I'm about to dispose of the entire plant, as I've had nothing but poor luck with it. What used to be a vibrant lovely lush green plant has become a failing scraggly yellow pathetic-looking plant :(

My guess would be you have thrips; I don't have a lot of experience with them personally, but the simplest and fastest way to get rid of them would probably be to spray the plant with an insecticide labeled for thrips. No doubt there are other ways.

Thrips? Oh brother! I think you're right, Mr Subjunctive. Thank you so much! By the way, I loved the monstera/philodendron blog - very informative and well-put together.

Sorry, but no -- he's wrong. Not thrips at all.

That's a rove beetle. It's a beneficial insect. Well, it is when it's outdoors.

In any case, it probably came along when the plant was sitting on the floor somewhere.

Beyond that, thrips are very, very tiny. You would have been exceedingly lucky to get such a detailed image of a thrips with your camera.

See here for various images

Note the characteristics of thrips, among them very slender wings with fringed edges.

Here is a link that might be useful: google for thrips images

Rove beetles do seem more likely.

Oh! I went out and bought systemic Bonide and treated the plant earlier today. Surely the rove beetle will be killed off as well? Was it harmful to this plant? Well, I'm just relieved to know it's not thrips afterall. Poor plant. I hope it makes it. It really used to be quite lovely. Thanks for the help.
