|Description: A rather large species with very distinct colouration making it impossible to confuse it with any other species in the region. The black eyes are ringed with white hairs. The carapace and legs are green in both males and females, and covered with white silky hairs. Tibia IV with one one dorsal spine which separates the species from M. ligurina which have two dorsal spines. Females and juveniles of both sexes have bright emerald green abdomens with a yellow median band which for the most part is filled with a green cardiac mark. Just before wintering, the young male moults into a light yellow colourform with indistinct longitudinal scarlet bands and spots on the abdomen. The male winter as subadult. The final moult takes place in May whereby the abdomen becomes shiny yellow decorated with three longtidinal vivid scarlet bands. Spiderlings are yellow with reddish spots, and resemble juvenile males somewhat. Adults are much less frequently encountered than immatures, especially males that have a very short season. Size: Female 12-15 mm; male 8-10 mm. Maturity: Males have a very short period in May and June, females from May to August. Habitat: Oak forests, often with undergrowth of blueberry and heather. Also on low vegetation in damp forest clearings, forest edges and moors.
