What's eating my friend's orchid?

Hi,

A friend sent me a picture of his orchid, which I've attached below, showing small green to black spots on the flowers a large chunks of the flowers that have been eaten away at. There is no damage on the leaves, it's restricted to the petals.

Any idea what's eating his flowers?
We live in London, UK and the plant is kept indoors. It is placed on a windowsill near to a kitchen bin, so he was suspecting fruit flies..

I've already advised him to change the plant's location and keep it isolated from the other orchids, which thankfully don't have any problems.

But it would be useful to identify the source of the problem, so he can treat the plant if necessary.

I've never heard of fruit flies eating flowers.

Do you guys have earwigs over there? It looks like earwig damage to me. And those little buggers can hide really well.

Yea I don't think fruit flies damage plants..

He also says that there have been lots of forest beetles around recently..some dead, some alive

No clue what a forest beetle is but if they eat flowers then that could be the culprit.

The feeding pattern indicates something that tears off bits and eats them rather than the eating pattern of, say, a Japanese beetle or many caterpillar that "laces out" the leaf. My first thought was earwig because they are excellent hiders and can do a lot of damage before they are found. They eat just abut everything...both good and bad bugs because they do eat the nasties. Problem is...they also eat things we don't want them to eat. They were the bane of my existence when I grew lots of dahlias.

It does look like earwig damage. Cockroach is another possibility.

Could be trips too.

Have thorough look on every tiny bits of the flowers and down, you may find one offender if it's not trips who will hide and are small.
