Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

Over the last few days I noticed a lot of chewed-up leaves on the
ground beneath our large 25 foot tree. Upon closer examination I
found the following larvae attached to the leaves, as well as some fly-
looking creatures (not sure if they're related to the larvae).

Can anyone identify the offending vermin? Should I be concerned about
this? What steps should I take to get rid of the infestation and save
the tree?

Is that a linden tree?

The procreating insects are Japanese beetles, which appear to be
skeletonizing the leaves.

The "larvae" on the leaves are spindle galls which are probably caused
by a particular mite or midge.

There is tons of information concerning the control of Japanese beetles
and leaf galls on the web. I am not at all sure what the best methods
are. Maybe someone here will chime in.
