A Royal Palace, A Caterpillar

Royal Palace in Amsterdam

What is now a royal palace in Amsterdam, the Netherlands, was built in the 1600s as an impressive City Hall.

The unusual caterpillar was found in the jungle of Suriname, South America.

What could possibly connect these two things on different continents an ocean apart? Not royalty, not even someone from the wealthy upper class; it was a little old lady named Maria Sybilla Merian (1647-1717), a lady well known in her time for her studies of caterpillars and their metamorphosis into butterflies or moths; and for her painted illustrations of them.

Having seen a few specimens of unusual butterflies in the collections of wealthy collectors, Maria decided to travel to South America to discover what kind of caterpillars became these beautiful butterflies. Her friends and acquaintances were horrified and tried their best to dissuade her. They argued that 1 she was too old to make a two-month sea voyage (at 50 she WAS old), 2 the trip was too dangerous (it WAS dangerous, what with storms, pirates, and probably inadequate food), 3 she certainly could not travel without a man accompanying her (she had already done so twice), and 4 the cost was prohibitive (it really WAS a lot). Reason number four was the only one she was concerned about. She made plans and apparently sold everything she owned except her art supplies.

When her friend, the mayor of Amsterdam, realized that Maria was determined to go, and probably that she could also bring him some new specimens for his own collection, he persuaded the city fathers to help fund her trip.

Upon her return to Amsterdam two years later she was invited to exhibit some of the insects and other small creatures she brought back with her. The exhibit was a huge success since these were things most people in Europe had never seen before. They were amazed.

What You See Is…?

When scientists began to take a closer look at the natural world all around them, they did not always agree on what they saw. They did not always accurately understand what they saw. They often jumped to conclusions, especially if they were still influenced by the belief in spontaneous generation. The old, traditional belief that living things could come from non-living things-–still held by many––caused some especially heated debates.

Based on what he, personally, had seen, he wrote a recipe for making mice! (Why anyone would want to make mice, I don’t know, I guess he wasn’t concerned with that.)

According to Dr. van Delmont, if you put a piece of sweaty, smelly underwear in an open mouth jar and added some wheat, in twenty-one days full-grown mice would emerge. This was considered scientific observation at that time; not quite the way Maria Sybilla Merian handled her observations of the transformations of caterpillars into butterflies and moths. She studied the caterpillars carefully, documenting with notes and paintings all of the changes that occurred. In fact, she thoroughly documented the entire life cycle…proving that caterpillars did not just ooze up out of the ground, but came from eggs that the butterflies and moths laid. Her method of research is still used today.

Strange Creature Spotted in Memphis!

We saw this 10 inch worm slithering along the sidewalk as we left the apartment in Memphis the other day.  Worm?  Snake?  Weird!  What a head!

Found out it’s called a Hammerhead Flatworm.  It’s an invasive species and eats earthworms.  I read that it’s mouth is somewhere in the middle of the body.  Did I say it’s weird?!
