Definitely one here to keep an eye out for!

Well, they are easier to photograph than birds and there are lots around at the moment so...

Enoplognatha ovata

Tegenaria species

...and this one, Steatoda nobilis - one of the few spiders in this country that will *bite if provoked. Sometimes called the False Widow. Found this one on the inside of the window frame!

* the following accounts are taken from the Natural History Museum's website:

Bite reports
The bite itself is not usually felt but, within a short space of time, a local burning sensation is followed by radiating pain ('far more severe than a bee or wasp sting', Warrell et al., 1991).
'Sudden onset of intense pain, radiating across thigh. Lasted 20 minutes with some swelling and a developing weal.'
'Bitten on left hand; within 3/4 hour developed swelling of palm including thumb and fingers with tingling in all fingers. Swelling on left side of face with tingling over face. Two small puncture wounds in the region of the swelling, surrounded by local erythema with small bluish tinge a few hours later.'
'Bite on arm (area red) immediate pain. Spread to chest - still stiff 48 hours later.'
'Burning sensation on the right side of ribs. Increased in intensity, like being scalded, stabbing pains spread first to armpit then down right arm. Also flu-like symptoms, aches, sweats, fatigue, perspiring, cold and shaky, sick and giddy (all in first 10 minutes). Face and right arm went purplish and slightly puffy. Bite mark raised with red area c. 5 or 6cm. After 1 hour, responded to Piriton but felt unwell for 3 days.'
'Bitten on the shoulder. Initially the top of my arm ached, then felt itchy. Ten minutes later my armpit became numb. The skin was hot and sticky and looked wrinkled. The tenderness and itchiness lasted for some days' (later said to be infected).
Frequency of bites
Increasing as the species spreads in the south and east of England.
