Bird-cherry Ermine Moth

[Tom Richards]

I drove past these mature Bird Cherrys today at a local recreation ground and was shocked by the infestation of moths and webs they are completely covered and have been completely defoliated .

 

I’ve not seen this before but reading on line apparently it’s a common pest. 
 

I can’t see the trees recovering from this ?

 

does anyone have  experience of this moth and have trees that have been stripped recovered ? Are there any particular actions that can be taken ?

Hi, I came across a similar infestation some years ago on a Bird Cherry a bit smaller than the trees in your pic while dog walking, first and only time I've seen it.. the tree was covered in silk and leafless but it did actually recover and hasn't been affected since, cheers.

Thanks for this I’ll keep an eye on them over the next month and see how they progress.

The damage they inflict isn't really a problem, its just the cosmetic effect and can look unsightly to some. In terms of the extent and effects in evolutionary terms for a species to destroy the plant it relies on is a big no no!

 

When  the caterpillars turn into adult moths in the coming months, the trees will start to recover – just in time for the adult moths to lay their eggs in them and start all over gain but not usually in the same trees. 

 

Google image the title, the adult is a stunning little thing!

Seen it this year in a still establishing mixed species farm hedge, be very surprised if the bird cherries survive 😐
