A spider caught a wasp on a ‘speechless’ dad’s windowsill before ripping it apart in its web.

James Power had just released the flying bug from his daughter’s bedroom in Hertfordshire on April 8 when a lurking arachnid struck.

Dramatic footage captured the moment a spider caught the wasp in its web before methodically pulling its prey in closer and closer.

After climbing on top of the wasp the spider then tore its victim’s head from its thorax while it was completely trapped.

James said: “Watching this spider take down a wasp on my windowsill left me feeling like David Attenborough.

“I'm normally the type of guy who would try and narrate in a funny voice or something and make a joke out of it.

“But watching this I was actually more or less speechless while it was happening.

“The wasp was on the inside of the window slapping against it trying to get out.

“I opened the window and as I closed it, the wasp flew to the sill and then the spider appeared and the fight started. It carried on for eight minutes or so.”
