Found this little one near the trickle vent this morning, it's a bit fiesty!
It's body is about 4mm. I have seen others, larger with similar markings on my patio umbrella, only at night, and they are camera shy. I remember in the summer a large black spider on the umbrella but was more fascinated than wanting to kill it. With all the hype surrounding False Widow spiders currently I wanted advice. I have an illness with my lungs and breathing sometimes is a task.
This is not a false widow, it is a missing sector orb weaver (Zygiella species), harmless & very common indeed around the exterior of houses (occasionally inside too), garden furniture, climbing frames, car wing mirrors etc...I should think every household in the country has at least some of these spiders.
Spiders aren't keen on being constrained in glasses as a rule, if it's very active & butting up against the glass, this is more likely due to a desire to escape, than aggression.
