Birch thing

A bud-like growth on Birch. I don't think it something the plant normally grows, so I wondered if it was a gall of some sort.

Species interactions

No interactions present.

I can't help with the bud

I can't help with the bud gall, but the red splodges on the leaves behind are the galls of the mite Acalitus longisetosus. It might be worth posting these as a separate observation.

Thanks for the advice

Thanks for the advice Syrphus, but I actually put up a picture of the red splodges yesterday (thinking it was some sort of rust).

Red gall on birch

Can't find the other posting but this does seem to be Acalitus longisetosus.

I am trying to get all UK plant gall postings in one place



This will hopefully increase the "visibilty" to people interested in plant galls and increase identifcation/confirmation rates

There are cureently over 550 records collected

Could you please tag any plant gall records "plant gall" or "plant gall causer" - without speech marks

Thanks in anticipation - appologies if you get multiple requests as I am trawling through past records.

If you feel reasonably confident in your id why not go to "other observations and confirm them - Following Derek's advice - if you go here to get to the next record for the same species just go to the top left and click next
