In such tough times, there are battles
0:07
for territory in the most unexpected
0:10
places.
0:14
As night falls in the Beaab forest, an
0:18
extraordinary crowd emerges.
0:28
They're baby flatted bugs. By day
0:31
they're barely visible, but at night
0:33
they swarm over the trees and start to
0:36
feed.
0:40
They drink sap and each settles itself
0:43
into a spot on the branch.
0:50
But even at this miniature level,
0:53
there's a battle for resources. And here
0:55
and there, fist fights break out.
0:59
This curious spat has never been
1:01
observed before.
1:07
For the most part, however, they feed
1:09
quietly. And as they feed, they excrete
1:12
unwanted liquid called honeydew. It
1:15
coats the branches and remaining leaves.
1:19
And this is very attractive to other
1:21
insects that are out and about at night.
1:32
And that in turn provides a feast for
1:35
mouse lemurs.
1:38
At around 60 g, mouse lemurs are the
1:41
world's smallest primates.
1:55
These are all males. The females are
1:58
fast asleep in tree holes and have been
2:01
for months. They can sleep right through
2:04
the dry season and they'll only emerge
2:06
when the rains come. It's a way of
2:08
saving energy.
2:13
So, for now, the males are on their own,
2:16
feeding on anything that will take them
2:18
through the lean times and waiting for
2:21
the day that the females awake.
