Called, among others, "flying rods", "skyfish" and "solar entities", these creatures are invisible to the naked eye and can only be noticed on slow motion camera and resemble a flying centipede.
"We were surprised at what we found when reviewing the video," said Matthew, who was aware of the existence of "flying rods" in the Internet and having seen documentaries done on the subject in TV's "Monster Quest" series.
"We did not know they were there until we reviewed the video footage.
"We don't even know if they were an insect specie or creature of some sort that holds an element of intelligence that interacts with other entities or animal species," Matthew said.
"I have one footage of a group of them together and you can see them turning at extreme speed. They even chased a bat away.
No one has got footage of this. It's never been seen before.
This bat was minding its own business until these rods appeared like it was terrified of them.
"Also, previous footages also using high speed cameras captured them in sparse environments.
But our Sabah recordings show for the first time that these creatures have very powerful sensors that prevent them from smashing into the walls of the caves like making U-turns at the last moment.
Insects can't do this," he said.
"The way they move is nothing like we know in the animal or insect kingdom or even aircraft in terms of speed. It's the fastest thing you have ever seen and can turn on a dine.
"Upon examining a blown up frame of their body, one can notice it has seven segments and look like they have wings, which is why they are called rods."
