And even though I didn't want to lose the group by stopping for pictures all the time, I couldn't miss this pretty beast sitting on a leaf in the woods 🙂

It's a common cardinal beetle (Pyrochroa serraticornis; 🇩🇪 Rotköpfiger Feuerkäfer).

At the annual retreat of the Planet Formation & Exoplanets department of @mpi_astro this week 🏰

The traditional hike was today, ahead of predicted bad weather: to Burg Löwenstein, 9km, 322m of elevation. Steep in the vineyards 🥵

Still some time for arthropods though: this is a European hornet (Vespa crabro; Europäische Hornisse).

And another mystery to end the weekend 🙄

This little one is very likely a running crab spider, genus Philodromus, but I'm not sure which species.

We have P. dispar in the garden, as well as P. rufus or albidus (they're hard to separate.

I suspect it's one of the latter, but ... 🤷‍♂️

This one's a puzzle though.

Obviously an aphid, not least because of the tubes at the back, the cornicules or siphunculi.

But which species? The light brown face & quilted black body should be easily recognisable, but iNaturalist's computer vision suggestions don't even come close.

Anyone an expert on these little suckers? 🤨

Well, that's unexpected 😳

Took some pictures earlier of a jumping spider I thought was Evarcha falcata, one of our regulars.

But checking it now, looks like it's actually Macaroeris nidicolens (🇩🇪 Kanarenspringer).

First seen in Germany in 1995 & then in the East End of London in 2002, hence the name Mile End jumping spider.

Finally, a mystery.

This spider was tucked up in a tunnel it made by sticking two edges of a leaf together.

Short of me destroying the tunnel or aggressively chasing the spider, this was the best picture I was going to get.

Its two front leg pairs were long & equal length, so perhaps a crab spider, but which species – ideas?

Also not new, but a pretty shot all the same, an ashy mining bee (Andrena cineraria; 🇩🇪 Aschgraue Sandbiene) investigating the first roses to bloom in the garden.

Speaking of that final moult, it was interesting to find the empty shell of a nymph underneath a nearby green leaf.

I photographed it in situ, then carefully removed it to get a better shot.

Whether it's the nymph of the same adult Issus coleoptratus in the previous pictures, that's a mystery I don't expect to resolve 🤷‍♂️

Hemimetabolism.

Not a new species, but nice to see the adult stage of this little planthopper, Issus coleoptratus (🇩🇪 Echte Käferzikade) finally.

As you may recall, the nymph stage has gears to synchronise its hind legs when hopping, but it loses these during the final moult – the adults use a different mechanical coupling.

Then, just before the sun set into the trees on the hills to the west, a small copper butterfly (Lycaena phlaeas; 🇩🇪 Kleine Feuerfalter) joined the scene, also to feed on the white flowers.

A nice end to a warm, sunny day 🌞
