When working in a school, this could mean any number of things, especially when standing at the corner of the corridor that leads to the staff room first thing in the morning before staff briefing... I replied with a tentative "Oh?"
"You've got caterpillars! They arrived in the post this morning, here you go!"
Deposited into my hand was a small box, which yes, did contain five very small caterpillars, much to delight; and much to everyone else's amusement when I announced my new arrivals during staff briefing.
Looks like they're getting ready to pupate
All but one are now chrysalides
Over the weekend, the fourth has caught up
After a bit of a fight with the string and the silk they had woven, we transferred them to the hatching habitat
All five had emerged when I arrived at work. We fed them with sugar water and banana.
The red liquid is what they have used to pump out their wings and then expelled.
All of the others flew straight out when we opened the lid, but this one seemed reluctant to go...
