The Liverpool Screw Towing & Lighterage Co. was a prominent Merseyside company that provided tugboat services for vessels operating within the Port of Liverpool, its docks, and the Mersey Estuary.
The company's name was shortened to Liverpool Screw Towing Company in 1957.
In 1966, the company was acquired by the Alexandra Towing Company Ltd.
It might look like it just arrived from a sci-fi film set, but, the Megarhyssa wasp is very real.
That thread-thin appendage trailing behind her? Is not a stinger, it’s an egg-laying drill, custom-built by evolution. Using it, the female bores through wood to reach the larvae of other insects hidden deep inside.
The female detects vibrations from the host, measures the depth like a living sonar system, and drills straight to the target.
Once she reaches it, she deposits her eggs directly into the unsuspecting larva. Once her eggs hatch, her little ones will dine from the inside out.
Just nature doing its job with unnerving efficiency.
