he says he has a -- fossil insect -- not evidence of current insects.
However,
for many years here I have half joked about:
The Martian sand flea

with
the titanium

exoskeleton

that
looks just like a little pebble in rocks and sand -- natures disguise --
which
is why we would never recognize such insects in Mars images.
One problem I have with his insect --- 20 inches long --- but it is a fossil in his estimation.
So whatever evolved,
is likely very small and hard to see.
Might only come out at night from -- microniches -- or hide in "microniches" waiting for prey.
If ice worms ever emerge under warm conditions to the surface,
then that would be one food source.
Insects can possibly burrow down deep.
... termite mounds and such as well ...
best to bring the image here from his work
