Metellina mengei
This record describes Metellina mengei (species). Recorded family: Tetragnathidae. Recorded order: Araneae.
Identification and Appearance

Metellina mengei resembles M. segmentata although on average M. mengei may be slightly smaller. Having said that, there is size variation in both species which creates an overlap. Mature M. mengei tend to predominate in spring and early summer (remember m before s ), mature M. segmentata tend to be most numerous in late summer and autumn, though some M. mengei can persist in this period too. Both species are very variable in appearance and can often only be separated by examining specimens with a strong hand lens or microscope. 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. If we cannot be certain of the identity of an image but it is likely to be a certain species, it is highlighted in a red box It is to be found all year round, but may be more prevalent over the winter and spring period through to early summer.

About Spiders: the wider group
Order-level background for Araneae, the group containing Metellina mengei. 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.
