The European spiders of the year 2017, Nuctenea umbratica (Clerck, 1757), and 2018, Steatoda bipunctata (Linnaeus, 1758), are presented. Both species were originally bark-dwellers, but became more and more synanthropic. Their appearance and character

Males and females are often subjected to different selection pressures for homologous traits, resulting in sex-specific optima. Because organismal attributes usually share their genetic architectures, sex-specific selection may lead to intralocus sex

Behavioral characteristics importantly shape an animals’ ability to adapt to changing conditions. The notion that behavioral flexibility facilitates exploitation of urban environments has received mixed support, but recent studies propose that betw

Summary A survey of ballooning spiders was carried out over a period of eleven years between 1994 and 2004. Altogether, 15,398 ballooning spiders, representing 103 species and 16 families, were caught with a 12.2 m high suction trap in an agricultura

Urbanization poses serious extinction risks, yet some species thrive in urban environments. This may be due to a pronounced developmental plasticity in these taxa, since phenotypically, plastic organisms may better adjust to unpredictable urban food

Pretensile forces were measured in individual threads of intact spider webs. In the orb web of Araneus diadematus forces decrease from mooring threads to frame threads and radii, a typical ratio being 10∶7∶1. The smaller number of radii in the up
