Just one new garden species so far on this warm, overcast, & drizzly day. But it's a doozy ... 🙂
This is a white plume moth (Pterophorus pentadactyla). It has many names in German, but I like Schlehengeistchen, or little blackthorn ghost 👻
Hard to capture, hidden in the foliage, but well worth the effort 👍

My private Newgrange 🌞
As we approach the northern summer solstice, we get to see sunlight flooding into parts of our house it normally doesn’t reach.
We live in a steep-sided valley & at certain times of the day, houses on the other side with angled roof windows line up with the Sun & reflect it horizontally into our living room.
And as the house doing it today has two such windows, we get double shadows 🙂

Well, I didn't have that on my May Day bingo card – a predatory jumping spider impersonating a noble worker ant 😱
This is likely Leptorchestes berolinensis (🇩🇪 Großer Ameisenspringer), & from its shape & the way it was running up & down the rose leaves, I was sure it was a large ant.
Then I downloaded the photos & counted the legs 😳

Finally! 🎉
I've been seeing male orange tip butterflies (Anthocharis cardamines) for weeks now, but they never stopped to be photographed.
Even this one today, on the Königstuhl, was flitting from flower to flower, making it hard to get close with my iPhone. But still ... 🙂
In German, they have the beautiful name Aurorafalter.

Despite the continued cool weather & apparent lack of much going on, lunchtime in the garden proved decently productive.
First, a small groundhopper nymph, likely genus Tetrix. Being more specific is tricky, but T. undulata, the common groundhopper (🇩🇪 Gemeine Dornschrecke) is my best guess. Alternatively T. tenuicornis or T. subulata.

Next, one of the bigger & buzzier flies in our garden – the common tachnid (Tachina fera; 🇩🇪 Schwarzfühler-Borstenfliege). Closely related to Nowickia ferox, which we also have, the latter being generally darker – hope to see one later.
I didn't manage to get a great head-on shot, but it very proudly displayed its bristly arse to me 🤷♂️🙂

Now turning to a couple of bees.
First, this red mason bee (Osmia bicornis; 🇩🇪 Rote Mauerbiene) was hanging around the new bee hotel, & may have been responsible for filling & capping one or more of the wooden holes & bamboo tubes.
Osmia bicornis are solitary bees & important spring pollinators.

Next a new bee species for me, albeit rather distinctive.
This is an ashy mining bee (Andrena cineraria; 🇩🇪 Aschgraue Sandbiene or Grauschwarze Düstersandbiene).
Another solitary bee species, albeit one that digs holes in the ground for its nest, rather than using wood.

Finally & rather more ominously for the bees, an early sighting of an Asian or yellow-legged hornet (Vespa velutina; 🇩🇪 Asiatische Hornisse).
Predators on bees, they've become so prevalent in Europe in recent years, the German govt has largely given up on trying to eradicate them. Reporting them is no longer mandatory in some states.
