I found several small holes in my strawberry leaves. Upon further
investigation, I found these creatures on the bottom of the leaves,
curled up. They are very small, 3-4 mm maybe. Yellowish-green body and
brown head. I don't know if they are caterpillars or larvae. I
attached a picture.

caterpillars = larval form of insect (mainly moth or butterfly) = larvae

I also found holes on the leaves of my hazelnut tree, so it's possible
the same thing is eating them but I am not sure.


Unlikely, probably two different things, holes on fruit tree leaves have
several different causes and if they are from caterpillars it is likely to
be two kinds as they tend to specialise.

Does anyone have a clue what they are? Are they dangerous to the fruit
or just the leaves? How do I get rid of them?

They are caterpillars, I don't know the specie. You can:

- pick them off and feed them to the chooks, the chooks will thank you very
nicely
- spray with BT, a natural control that does not hurt anything else but
caterpillars that eat it
- spray with insecticide which may hurt other organisms (eg bees) especially
if you spray too much when they are around, if doing this use one of the
milder sprays such as pyrethrum and don't go crazy with it.

Different grubs eat leaves and burrow into fruit, you don't necessarily get
both. Generalising, the one grows into a moth or butterfly the other into a
fruit fly.
