Con-trail over Mongorrey |
I can almost predict that the first hoverfly of the year will be a female Eristalis tenax, and sure enough, I spotted this one today on a Dandelion:

I went up to see if there was any frog spawn at the usual places, but none was visible, although I have seen a few frogs at night. I did, however, see a few midges in loose clouds:

This is still a good time of year to see lichens before the green growth obscures them. I found a large specimen of Peltigera membranacea (Rabbit's-Paw Lichen):
Peltigera membranacea - 'Rabbits-paw lichen' |
The underside of the thallus is covered with spiky rhizines, which are used as anchors:

Evernia prunastri can be distinguished from other similar species by the twin-forked branching structure:

Dotted Border moth |
The Dotted Border feeds on a wide range of broad-leaf trees as a larva. I'll leave you to work out where its name comes from.
Here's the result of living in a wet climate:
Peziza domiciliana |
Peziza domiciliana is a fungus which is most commonly found indoors, growing through concrete. This specimen is happily growing in the boot of my car.
New to my species list (and not previously recorded in Ireland, although I find that difficult to believe).

As usual, beautiful and informative photographs Stuart - I have sent a link to my friend who is very active at our local Nature Reserve (Foxglove Covert LNR if you fancy a look at their web site).
We are busy raising money for them by doing quizzes on moths, butterflies, wild flowers, birds etc., and the next one I intend to do (cryptic clues which I am etting) is on mosses and lichens. I have a book and there seem to be quite a lot which are indigenous to the UK. Thanks for popping over to see me. Loved your comment.
Beautiful - it's nice to see Donegal in the sun (even if we'be been suffering under grey skies on the other side of the high - until today when it is sunny again in Yorkshire).
Is that Peltigera really tha colour, or is that frost on it (my lawn looked like that this morning)?
Gill: the Peltigera is very pale grey/blue when the thallus is new. It later dulls down to a slate grey. Other Peltigeras are black, brown, green or dark grey. When I saw my first specimen (a glossy black P. canina with brown 'fruits') I had no idea whether it was plant, fungus or lichen. It seems that some Peltigera species can discard their captive photobiont(s) in favour of another as they develop. That will alter the appearance and colour. (I actually wonder if some of what we're identifying as separate species are actually the same fungus, but in association with different photosynthetic partners!)

That's actually the reverse of 'host modified morphology' where a fungal rust can manifest differently depending on which host it has chosen.
" When I saw my first specimen (a glossy black P. canina with brown 'fruits') I had no idea whether it was plant, fungus or lichen." I know what you mean. I thought my first Peltigera was a funny liverwort!

I believe something similar happens with fungi, especically rusts, which have two hosts, and the two(+) forms are given different species names.
