I found this tiny (about 3-4mm) bug inside a pot of a lily bulb 13th January.

I wonder now whether it could be Arcitalitus sylvaticus or A. dorrieni.
We have a picture of Arcitalitrus sylvaticus in Bug File pictures that looks very much like mine, but there is no size mentioned.. I didn't find pictures though of A. dorrieni on the web so I cannot compare with mine.
Both species seem to have been introduced from Australia in many parts of the world with the plant trades..
