Recently, I was contacted by a naturalist in Sicily who shared a series of exceptionally high-quality photographs of a female ladybird spider ( Eresus ) during what appeared to be an interaction with a spider wasp.

Diversity survey of Pholcus spiders (Araneae, Pholcidae) from eastern Sichuan and neighboring areas, with descriptions of six new species

Abstract

Thirteen spider species of the genus Pholcus Walckenaer, 1805 are reported from a diversity survey in eastern Sichuan and neighboring areas (northeastern Yunnan and western Guizhou). They belong to three species groups and include six newly described species: Pholcus qiaojia Li, Li & Yao, sp. nov. (♂♀, Yunnan) in the bidentatus group; P. aba Li, Li & Yao, sp. nov. (♂♀, Sichuan) and P. wenchuan Li, Li & Yao, sp. nov. (♂♀, Sichuan) in the crypticolens group; P. mengding Li, Li & Yao, sp. nov. (♂♀, Sichuan), P. miyi Li, Li & Yao, sp. nov. (♂♀, Sichuan) and P. yaan Li, Li & Yao, sp. nov. (♂♀, Sichuan) in the yichengicus group. P. bidentatus Zhu, Zhang, Zhang & Chen, 2005 is recorded from Yunnan for the first time and P. kunming Zhang & Zhu, 2009 is recorded from Guizhou and Sichuan for the first time. Detailed diagnoses, descriptions, photomicroscope images, and DNA barcodes of all newly described species are provided.
