I saw two orcas swim down Strangford Lough a couple of weeks ago. This is one of them, photographed by Adam Osborne. – Patricia McKane, Strangford, Co Down
Amid great excitement a pair of killer whales swam up the lough on an incoming tide and left with the outgoing. It is said that they are the remnants of a pod of eight that frequents the Hebrides and was last seen in the lough in 1987 and before that in 1962. – John Wilson Foster, Portaferry, Co Down
I rescued this baby robin from the mouth of a rogue cat and it survived and enjoys being fed in the garden. – Liam Kane, Blanchardstown, Dublin 15
This critter landed on my neck while working outside and I couldn't figure out a name for him. – Dan O'Connor, Letterkenny, Co Donegal
It's the two-banded longhorn beetle. The larvae live in dead wood and take two or three years to mature.
My son Conor was cleaning a corner of his garden when he came on a nest with two young shrews in it. He moved them to a box and tried to feed them, to no avail. Later he put them back and within minutes an adult shrew came looking for them. – Alan Dunne, Mountmellick, Co Laois
It's better to leave unattended nests alone.
I found this creature in my house. It was about 2cm long with a green fluorescent underbody. – Mary McCarthy, Castletown, Co Laois
It was the green tiger beetle.
There were dozens of emails with photos of the cockchafer beetle, also known as the May bug, which flies at this time of year. It chews the leaves of various trees but its shrimp-like larvae, which are buried in the soil, can damage crops.
