Spotted in my back yard By the collour it must be dangerous ,so we remove it to a very safe distance from the yard


He keeps the calm,looks at us in our strange,backyard adventures,but he dont play with insects,in these winter days he prefer staying in the sun :-)

Lovely! The hairs on this one are probably not dangerous, but may irritate sensitive skin.
