I wonder, what is this small bug a few millimetres long? A few times this summer I’ve felt a small, sharp bite on my arm when working in the garden, to find that one of these is the culprit.

Kevin Healion, Templemore, Co Tipperary

It’s the common flower bug, Anthocoris nemorum, which will bite humans. It feeds on aphids and red spider mites and is used as a biological control in the garden.

The crustose lichen, Fuscidea cyathoides

I saw this unusual lichen on Tully Mountain, Co Galway. What is it called?

Brian Graham, Dublin 13

It’s the crustose lichen, Fuscidea cyathoides. There doesn’t seem to be a common name, although it is widespread in Ireland.

Cardinal beetle

I’ve found a number of these 4-spotted insects in the garden.

Brendan Dollard, Ashbourne, Co Meath

It is one of the cardinal beetles, Endomychus coccineus, called the false ladybird because of its resemblance. It is a fungus eater.

The convolvulus hawkmoth is a migrant from Africa

This monster landed on my arm while I was cutting the grass and gave me the fright of my life. It was 60mm from wingtip to wingtip.

The convolvulus hawkmoth is a migrant from Africa. It is one of the largest hawkmoths.

We found this skull on the “hole in the wall” (burrow) beach in Sutton, but don’t know what animal it came from.

Ciarán Culhane, Cabra, Dublin 7

It’s not a skull but looks much more like the pelvis of a bird.

Hummingbird hawkmoth caterpillar

I spotted this caterpillar on a pavement near the Merrion Centre in Dublin. The chances of him being squashed were high so we put him in the hedgerow.

Isabelle Wheatley, Rathmines, Dublin 6

This was the first report of a hummingbird hawkmoth caterpillar to Eye on Nature. Alas, it will probably not survive our cold winter.
