Tiny insect hatchlings that just hatched out from the white silky egg sac shown in the pictures. 70 baby insects and about 2mm in length each. Black legs, reddish brown body with 2 yellow vertical lines at the abdomen, thin and long antennas, a pair of small transparent structures on their thorax that looks like their wings. See last picture of close-up to see the "wings". They are Bark louse of the order Psocoptera.
Trees of Kinabalu National Park, Kundasang, Sabah, Malaysia.
Online reference stated that bark louse started as wingless insects but my spotting shows that they are developing wings early. Maybe this species is different from other Psocopteran species. >>>Map accuracy : 200 m radius.
Did you notice that most of the are pointing outwards? Why would they do that? I think that as they are hatchlings they may get the striped abdomens in their next instar, as in the linked images. They may be the same.
Thank you KarenL.
martinl, thank you too for suggesting it's order, your suggestion really matches their description.
This species might be a new species which defies what science know about Psocopterans.
Chun, this is really quite unusual. They seem to be forming two pairs of wings. They would not be from a modern order (with metamorphasis) because they are a nymph. I think you need to consider barklice (Psocoptera) consistent with long antennae. I admire your excellent analytical skill.
