I was trimming trees last month when I saw this insect. It was 4-5cm long.

It’s a sawfly, the female wood wasp also called the horntail, which uses her ovipositor to bore into pine trees to lay her eggs. They hatch and remain in the tree for 2-3 years, from which they emerge as fully grown sawflies.
I watched a snail trying to get down a gap in the decking but it was not going to fit with its shell. Why would it not leave the shell behind?

The shell is attached to the snail and grows with it.
We came across these beautiful spiders in the grass in Portumna Forest Park.
– Ava Gleeson, Oranmore, Co Galway
It’s the raft spider, Dolomedes fimbriatus, a hunting spider which waits at the water’s edge with two feet in the water to catch ripples from prey. It then runs across the water to attack sticklebacks, water insects or snails.
Hiking on Leenane Hill in Connemara recently we came across these colourful plants but don’t know what they are.

It’s a fungus called the small stagshorn, Calocera cornea.
Will this caterpillar survive the winter?
– Barbara Browne, Knockmore, Co Mayo
It looks like the caterpillar of the large yellow underwing moth, which will feed until mid-winter when it goes into hibernation. It will complete its growth in spring, when it pupates and the moth emerges in June.
I saw this big fella on the beach at Castlefreke in west Cork after the Lorenzo storm. It was larger than anything I’ve seen airborne around here. I also counted 58 Portuguese men-o’-war along the length of the beach.
– Mary Callaghan, Clonakilty, Co Cork
Experts think it might be the remains of a very large insect like a locust or grasshopper.
