Spider fans – I need your help!

This tiny one is a juvenile orb weaver, but despite the apparently distinctive pattern of spots and patches, I can't make a good genus-level ID, let alone species 😱

Some common features with each of Araniella, Enoplognatha, & Macrophya, but nothing definitive.

A small spider seen from above and to one side, sitting in the middle of its web. The spider is mostly yellow green, including the prosoma and legs, while the back of the opisthosoma is textured brown with pairs of yellow-green patches between, all bordered by five distinct black spots on each side.

Look, ma – it's my shadow!

This jumping spider was patrolling the ivy where many insects are flying today.

ObsIdentify is 100% sure that it's Evarcha falcata, but I'm siding with iNaturalist's 98.4% confidence that it's Carrhotus xanthogramma (🇩🇪 Wipfelspringer) – females come in many colour forms.

A jumping spider seen in half profile slightly from above, on a green ivy leaf, casting its shadow from left to right. The spiders is hairy and reddish-brown overall, slightly lighter on the prosoma, and with many long white hairs below the main four eyes, on the face, and on the palps and forelegs. The sides of the prosoma are slightly lighter brown and there are fine black hairs sticking vertically up on the dorsal side. The opisthosoma is darker red-brown overall, with very fine black hairs above, and a black tip to the abdomen. There is minimal patterning visible at this angle. The legs are reddish-brown, with vague bands of black and white at points, and are also hairy. The same spider seen from above, showing the contrast in colour between the prosoma (different shades of brown with some darker patterning now visible) and the opisthosoma (a more uniform red-brown with small dark markings at the base of the long, fine, black hairs, but only slight banding patterns otherwise). Overall, the legs more resemble the prosoma in colouration. The same spider seen from in front, with the classic jumping spider curious stare from its two central large eyes and the smaller side pair. Those are slightly out-of-focus, while the palps covered in white hairs are better seen. The many dark hairs poking up from the top of the prosoma, giving the spider its punk look, are also partly visible, but out of focus.

'Tis the season for big spiders – a cross orbweaver (Araneus diadematus; 🇩🇪 Gartenkreuzspinne), one of many currently making webs around @mpi_astro@wisskomm.social atop the Königstuhl.

These come in many shapes & colour forms, but the white cross on the dorsal side of the opisthosoma is characteristic.

Another hot & windy day. A few arthropods emerged in the evening, albeit no new species.

First, the eternally-cute woodland jumping spider (Evarcha falcata; 🇩🇪 Bunter Sichelspringer).

I also saw a huge robber fly on the same rose branch, but the noise of the camera turning on scared it off before I got a shot 🙄
