Ero aphana

This record describes Ero aphana (species). Recorded family: Mimetidae. Recorded order: Araneae.

Identification and Appearance

Ero aphana - Ero aphana

Ero aphana grows to about three millimetres long, the females being slightly larger than the males. The sternum is dark coloured with radiating pale markings in the posterior half and a larger, irregular pale blotch in the anterior half. The abdomen is broad and globular, light grey with darker brownish grey patches, two pairs of tubercles and sparse hairs growing out of orange spots. The legs are hairy and pale coloured with dark bands and one thin orange band. The front two pairs of legs bear a marginal row of long, curved spines. Where an image appears in a red box, this denotes that it is likely to be this species, but that this cannot be said with certainty - this species needs microscopic examination of an adult for a secure ID. Ero tuberculata is very similar, with two pairs of tubercles on the abdomen but is found later in the year, from July to October with female persisting into the winter. Although E. tuberculata has not been found in VC55 yet it is probably extending its range northwards and confirmation therefore requires microscopic examination of adult specimens. Requires microscopic examination of adult specimens. Dry lowland heathland and other vegetated habitat such as gardens. E. aphana has been typically found on dry heathland in the building and mature phases, with some patches of bare stony ground. Recent records have been from a variety of dry habitats, including gardens and brownfield sites. All year, but both sexes may be found most readily as adults from April to July, females persisting into August. Since 2000 it has started to appear widely in southern England, and as far north as Nottinghamshire. This species appears to be increasing rapidly, spreading to new habitats. This is a RDB2 species. 141 British records for this species to 2015

About Spiders: the wider group

Order-level background for Araneae, the group containing Ero aphana. Species-specific details appear above.

Group overview

As of 2023, 51,673 spider species in 136 families have been recorded, though an estimated 150,000 species exist. Spiders rank 7th in total species diversity among all organism orders. Only 0.5% of spider species pose any risk to human health.

Ecological role of the group

Spider venom contains complex peptides with diverse pharmacological activities, making them valuable for drug development research. Spiders produce up to 7 types of silk from specialized glands. Spider silk genes have been inserted into mammals and plants for biotech applications.

Economic and practical significance of the group

The global spider community kills an estimated 400-800 million tons of prey annually (2017 study). Spiders provide billions of dollars in natural pest control for agriculture. Spider silk is 5× stronger than steel of the same diameter, driving a biomaterials research industry.
