Black Thrips - Hoplothrips

Black Thrips - Hoplothrips
Hudson, Hillsborough County, New Hampshire, USA
February 3, 2006
Size: 3 mm head to tip of tail
Found in a finned tree fungus.

One thing I found out about thrips, they can climb very well. Both this one and a red one I shot crawled right up the side of the plastic deli container and down the outside. I never did catch up with this black one.

Moved tentatively; thanks much for helping us with thrips, Kara
Moved from Tube-tailed Thrips.

Looks like Hoplothrips!
Do you know the exact species of fungus they were found on? In Florida we have been finding a close relationship between Trichaptum biforme fungus and a thrips of the genus Hoplothrips, probably Hoplothrips smithi, looks a lot like your picture!

 
I'm afraid I'm pretty ignorant about fungus ID, Kara.
I should make an effort to learn, though, in order to establish host relationships.

How to find those?
May I know how do you collect the fungus and how to get the thrips? I need to collect these fungus feeding thrips, having a hard time to find their habitat. Do you scoop off the fungus then examined it for thrips randomly?

 
Yes, I just collect the fungi randomly.
I've never noticed thrips till I begin pulling the fungus apart looking for beetles :-)

 
thanks :)
If you wonder into a forest, how do you spot the fungus? Those you collected are not mushrooms aren't they? Do you have a picture of the fungus growth? :)

 
I think all the thrips I've seen have been on tree fungus.
Look on downed trees and stumps for the small, ruffled fungi. As I recall the thrips have been in/on the types that are closely overlayered, giving the thrips a place to hide. Also I think all have been found on moist, somewhat deteriorated fungi. Click through these pages to see some examples of tree fungi.

Tube-tailed thrips?
I wonder if this is a tube-tailed thrips in the family Phlaeothripidae.

 
Big group
There are some 3,000 known species in this thrips family. Lots of other interesting facts and illustrations here, including a view of thrips wings, which are fringe wings much like the Fringe-wing Beetles have.

As for the family ID, these are said to have a fringe of setae at the tip of the posterior "tube," which this one appears to have. I can see a little dust or debris stuck on it I think.
