Usually National Biodiversity Week in Ireland begins on a Saturday and ends the following weekend. However, this year it is a two-week event which began the week before last and will be ending next Monday, June 1, the June Bank Holiday. However, it was only late last week that the cold Arctic winds abated and a tropical current took over, and what a weekend we had. The birds are nesting now and are interesting to watch – such as these Jackdaws nesting in one of our chimneys:
Also, the insects are now making their presence felt – keep an eye out for this creature:
This is the largest moth species most people encounter in Wicklow and is far bigger than people expect Irish moths to be –
However, although it’s large there are several much larger species found in Ireland, and the largest that does visit Ireland, albeit only occasionally, the Death’s Head Hawkmoth, is about twice the size of this species and far more robust.
Moths are not the only large insects flying about our short late May nights – you can still find Maybugs, aka Cockchafer beetles blundering about and crashing clumsily into windows, cars and the occasional forehead. They are not our biggest beetle species, but they are probably our most common big beetle species, but they fly for only a short time in late spring and early summer, spending most of their lives as white grubs feeding on the roots of plantains and dandelions.
I know people might be wondering, “where the hell has he gone without a word about Biodiversity Week?”. Yes, it is late in the day, but unfortunately for me Biodiversity Week coincided with a heavy week of non-biodiversity related chores, and only today am I free to write and enjoy it all. Remember, the week is only designed to get you interested in biodiversity, so if you are already reading this, then it’s a case of “mission accomplished”. Also, a number of people have been in touch and I have yet to respond, so please don’t be offended if you have not heard back yet, your messages are not being ignored, and I am delighted to receive them. First things first, I received a lovely message from Ruth Finnerty to say she had found a Cockchafer beetle in her living room and had been able to identify it using this website, which is terrific news for me, because that’s what the website is for. Thank you, Ruth! Cockchafers are on the wing now in the warmish evenings, and this year they really live up to their alternative name of “Maybug”.
According to the famous 19th century French naturalist, Jean-Henri Fabre, people would use the grubs to cure toothaches. If anybody tries this remedy, please let me know the results.
Evening time is the best to see Cockchafers as they blunder into lights and windows. However, there are other remarkable creatures out there. Look on the flowers for some real wonders. In the photo below you can get some idea of how tricky it can be, and how observant you need to be. Can you see the two spiders in the photo below. If you can only see one, then you need to know that the other is much bigger.
On this occasion I was fortunate enough to see them mate, which involved the male climbing down behind the female’s bulbous abdomen and putting his sperm directly into her reproductive orifice with his palps, the little claw-like, antennae like structures beside his head. He has to be careful because she will eat him if she can. But there are much smaller creatures that are just as interesting, and I urge you to look at your flowers very carefully to see some very important little insects, pollinating beetles to be exact.
