I found these on Tramore beach in Donegal. They were all about the size of a thimble, with the consistency of thick clingfilm. – Susan Wolfe, Portnoo, Co Donegal
They are marine organisms called salps, which are part of the zooplankton. They feed on phytoplankton and are important in the biological cycle of the ocean as they control phytoplankton blooms.

Although I’ve seen grey partridges before, I’ve never seen a red-legged one. That’s what I think this one in my garden must be. – Gary Hill, Mullingar, Co Westmeath
According to Birdwatch Ireland, the red-legged partridge is indigenous to southwest Europe, and was introduced to Ireland where breeding takes place, mainly in Meath, Kildare and Wexford.

Yes, it is a water rail and it may have been the victim of the current avian flu.

What is this insect? – Ann Moran, Templeogue, Dublin
It’s the larva of the invasive alien harlequin ladybird. You should destroy it and any others like it as it preys on native ladybirds.
