Zora silvestris

provided by wikipedia EN

Zora silvestris is a prowling spider in the family Miturgidae which is found in Europe and Central Asia.[1]

Description

The females are 5 to 7.7 mm (15 to 310 in) in length, the males 3 to 4 mm (112 to 16 in). The epigyne has a quite distinct groove.[2] This species and the related Zora spinimana are difficult to identify from each other, Z. silvestris is more grey coloured than the warm yellow colouration of Z. spinimana. The darker legs of Z. silvestris are usually quite obvious. The two dark lateral bands on the carapace of Z. silvestris are broader than those on Z. spinimana and the prosoma on Z. silvestris is more contrastingly marked.[3] Z. silvestris has two pairs of spines on metatarsi I and II, the other species of Zora in Britain have three.[4]

Biology and Habitat

In Great Britain, Zora silvestris occurs on dry heathland, most commonly encountered in mature heather. A stronghold of the species is Sherwood Forest where it is found with larger numbers of Zora spinimana in mixed heather and grassland where the encroaching scrub had been cleared. Adults of both sexes are found from May to July, although a female has been recorded in September.[5]

Distribution

Zora silvestris is found from western Europe eastwards into central Asia.[1] In Europe, it is a widespread species from western and central regions and north into Sweden although encountered infrequently.[2] In Great Britain it is rare, recorded from five sites in southern England, the most northerly being Sherwood Forest. The species rarity may be exaggerated due to the difficulty of distinguishing it from Zora spinimana.[5]

Zora silvestris ( Norwegian )

Zora silvestris er en edderkoppene i gruppen (familien) Zoridae.

Utseende

Zora silvestris er en middelsstor og forholdsvis kraftig edderkopp. Hunnen er 3,5-4 millimeter lang, mens hannen er litt mindre. Forkroppen har et bred mørk langsgående midtfelt, som har et lysere felt midt i. Bredden på det lyse midtfeltet er lik med de mørkere feltene ved siden, og står i klar kontrast til dette. Den er litt snarlik en liten og lys ulveedderkopp (Lycosidae), men øynenes plassering skiller den fra disse. De åtte øynene er ordnet i to rektangler, et mindre, fremre og et større, bakre som delvis overlapper det fremre.

Beina er nokså kraftige, gjerne med ganske lange, mørke børster. Ytterst er de noe mørkere enn nær kroppen. Et av kjennetegnene er at ihvertfall de to fremste beina har noen mørke langsgående striper.

Levevis

Zora silvestris er aktiv om dagen (dagslys), den lager ikke fangstnett, men jakter i det fri i lavvokst vegetasjon. De trives helst på tørre kalkrike habitater som gressletter, sanddyner, veikanter og langs skog.

Hunnene spinner en flat, hvit eggsekk av edderkoppsilke, legger eggene sine i den og stiller seg over den for å vokte den til eggene klekkes.

Utbredelse

Zora silvestris finnes i Europa og østover til Sentral-Asia. Den ble første gang registrer fra Norge ved i Telemark, oktober 2010. Den finnes lengst i sør, men er trolig forholdsvis sjelden i Norge.[1]
