Dandelion Time

Up until last week it was still quite cold, but finally the weather has improved and at last we are getting proper warm spring weather. It’s that special time of year, the height of the great spring dandelion blooming. Dandelions support the vast majority of pollen-feeding and pollinating insects to a degree impossible to any other spring flowers. It’s great to see these important plants are finally starting to get the recognition they deserve:

They are beautiful flowers too, and give us a bright yellow landscape. Other flowers are starting to reach their full bloom too – here, for example, are Bluebells, the true wild bluebell which is quite common in Wicklow and possesses a beautiful scent, unlike the similar-looking Spanish Bluebell:

That butterfly is a Peacock (Inachis io) and it soon gave up the bluebells to feed on dandelions again.

This is also the time when the cherry trees are candyfloss pink from blossom, and they really do brighten the place up a good bit:

However, as beautiful as it is, it’s also important to remember spring is a time of high drama. At the moment you have a good chance of seeing the rare Tawny Mining Bee, which I mentioned in the last post. The male bees have now passed on, and the females are pregnant and busily constructing their nests, which are burrows. The mouth of each burrow is surrounded by a mound of soil, sometimes quite a lot. Tawny Mining Bees are parasitised by Cuckoo Bees, such as Nomada panzeri. They lay their eggs in the nests of the Tawny Mining Bees, and their young feed on the larvae of the mining bees. Here is a Cuckoo Bee, in the foreground, watching for an opportunity to get into the nest of a Tawny Mining Bee, but the owner is watching from the entrance:

As I tried to get a closer photo I accidentally scared the Cuckoo Bee off, and the Tawny Mining Bee decided it was safe to emerge:

These bees are usually gone by May, so now is the time to look for them. Next year’s generation will soon be hidden underground awaiting their time to fly in the sunshine.

 

Make a Meadow

Last year I made a meadow in my garden with a lot of help from my brother, and the results were spectacular as all sorts of insects were drawn in to feed and collect pollen, and hunt. It’s worth considering doing, and here is a video I made of it, with some nice music from Tchaikovsky’s Waltz of the Flowers:

Among the flowers are phacelia, buckwheat, poppies, marigolds, anthirrhinum, stock and buddleia bushes. Among the insects in this video are Buff-tailed Bumblebee, Red-tailed Bumblebee, White-tailed Bumblebee, Carder Bee, Honey Bee, Greenbottle fly, Large White butterflies, Green-veined White butterflies and a Common Blue butterfly.

And there is also a species of solitary wasp not often seen in Ireland near the end of the video.

April Transformation

We had a very cold and somewhat wet March, and April has been somewhat similar, bright and sunny but often windy and chilly at the very same time. However, a huge change is underway and spring is unfolding by the day and the hour. Only a few days ago I was delighted to see a queen Carder Bee (Bombus pascuorum) sunbathing on some bare ground among the violets.

A furry queen Carder Bee, which usually appears later in spring than the much larger Buff-tailed Bumblebee queens. This is very much the spring bumblebee.

Particularly delightful is the sight of Tawny Mining Bees (Andrena fulva) on the wing.  Usually males appear first, but this year I spotted a big furry female days before the first male. This is officially our rarest species of solitary bee, and as a result the National Biodiversity Data Centre are looking for recorded sightings from the public.  Here is a link to the record sheet, which is easy to follow and make submissions on: http://records.biodiversityireland.ie/submit_records.php?fk=SolitaryBeesStandard&caching=cache

And here is a photo I got two days ago of a female Tawny Mining Bee:

There is a similar but smaller species of mining bee also appearing right now, the Early Mining Bee (Andrena haemorrhoa). The males are very similar to the Tawny Mining Bee males, but much smaller and lack the white beard. The female is very beautiful, and here is a photo of a female from the same day as the Tawny Mining Bee photos:

A pretty female Early Mining Bee. She is much smaller then the female Tawny Mining Bee, and about the size of a male of that species.

Also buzzing around the lawn, feeding on dandelion flowerheads is a small and somewhat sinister-looking wasp. This is in fact yet another bee, but for the mining bees it is indeed sinister, as it’s a parasitic bee which lays its eggs in the nests of mining bees, its grubs killing and eating the mining bee grubs. This particular species of cuckoo bee is Panzer’s Nomada (Nomada panzeri):

But it hasn’t all been bees. Despite the cold some sunny days have warmed up sheltered areas enough for migrating butterfly species to begin flying about. So far I have only seen two butterfly species, and this one is the second, a Peacock (Inachis io):
