An Australian man thought he saw a clump of sticks or bark dangling from his back door. When he took a closer look, he saw that it was moving.
His story was reported in Yahoo News Australia.
The man first took to social media to post the strange sight on his door.
He says about it,
"Just seen this alien thing outside my back door, it moves so it’s alive," "I was freaked out when I saw its head. I thought it may attach but it moves very slowly."
Eventually, the Australian Museum was able to provide an answer for the strange case of the moving twigs.
The insect was a case moth (also known as a bag moth or bagworm). The moth attaches itself to fences and doors.
The case moth makes its home from leaves and twigs arranged lengthwise. They feed on plants and lichens.
They are primarily found in Eastern Australian states and territories.
They are not a danger to humans.
