Metellina segmentata

This record describes Metellina segmentata (species). Recorded family: Tetragnathidae. Recorded order: Araneae.

Identification and Appearance

Metellina segmentata - Metellina segmentata

4-8mm (female), 4-6mm (male). Usually has yellow, red and orange tones on the abdomen. The carapace has a dark tuning fork mark in the centre. Metellina segmentata closely resembles M. mengei . Mature M. mengei tend to predominate in spring and early summer, mature M. segmentata tend to be most numerous in late summer and autumn, though some M. mengei can persist in this period so the season is not a reliable way to separate the two species. Male M. mengei have a fringe of long hairs beneath the fore tarsi and details of the palps differ from M. segmentata . When the underside of females is checked, the black stripe beneath the abdomen of M. mengei extends forward beyond the point of the epigyne, whereas in M. segmentata the strip ends at the epigyne. However the only reliable means of definite identification of these two species is by examination of the genitalia. Found in woods, gardens and wasteland amongst any vegetation or structure where it can build its web. It is to be found all year round, but is more prevalent from summer and through the autumn. This spider spins orb-shaped (rounded) webs. During the mating season the male moves onto the web of the female. https://www.flickr.com/photos/63075200@N07/sets/72157632137729227/

About Spiders: the wider group

Order-level background for Araneae, the group containing Metellina segmentata. 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.
