Neurigona sp (unverified) |
Several of these flies were spotted on a mid-sized tree trunk at the foot hill of Bukit Larut (formerly known as Maxwell Hill), Perak, Malaysia. The tree bark seemed whitish and powdery. The body length of the fly is about 4 or 5 mm, maybe smaller. It had been observed to prey on smaller insects, where a smaller insect is sucked up on its mouth.
Neurigona sp, male (dorsal), unverified |
The overall appearance also look like Sciapus sp; however, the wing shows that it is not.

The ovipositor is a feature of the female. Female Neurigona sp lay eggs in the tree bark.
