The Phenological Records on Eresus Cinnabarinus (Olivier, 1789) (Araneae: Eresidae)

The velvet spiders: an atlas of the Eresidae (Arachnida, Araneae)

The family Eresidae C. L. Koch, 1850 is reviewed at the genus level. The family comprises nine genera including one new genus. They are: Adonea Simon, 1873, Dorceus C. L. Koch, 1846, Dresserus Simon, 1876, Eresus Walckenaer, 1805, Gandanameno Lehtinen, 1967, Loureediagen. n., ParadoneaLawrence, 1968, Seothyra Purcell, 1903, and Stegodyphus Simon, 1873. A key to all genera and major lineages is ...

A new ladybird spider from Hungary (Araneae, Eresidae)

According to the most recent taxonomic literature, three species of the genus Eresus are known in Central Europe, Eresuskollari, Eresussandaliatus and Eresusmoravicus. We recognized a fourth distinctive species from Hungary, which is described as Eresushermani sp. n. Eresushermani has an early spring copulation period, females have a light grey (grizzled) cephalothorax due to a heavy cover of l...

Dramatic histological changes preceding suicidal maternal care in the subsocial spider Stegodyphus lineatus (Araneae: Eresidae)

Parental care entails physiological costs to the mother. These costs, even if dramatic, are usually reversible and do not result in mortality of the mother. In the spider Stegodyphus lineatus Latreille 1817 (Eresidae), maternal care is extreme and irreversible: mothers regurgitate food for the young and then die when consumed by them (matriphagy). We examined whether the mother’s midgut tissues...

Herbarium records are reliable sources of phenological change driven by climate and provide novel insights into species' phenological cueing mechanisms.

PREMISE OF THE STUDY Climate change has resulted in major changes in the phenology of some species but not others. Long-term field observational records provide the best assessment of these changes, but geographic and taxonomic biases limit their utility. Plant specimens in herbaria have been hypothesized to provide a wealth of additional data for studying phenological responses to climatic cha...
