| Hickory Horned Devil |
Wikipedia: As the caterpillars age, they feed during the day. They molt 5 times. Each instar is different, but on their sixth and final instar they become a bright green color, with huge black-tipped red horns, earning them their common name "hickory horned devils". They feed heavily on their host plant and can grow up to 15 centimetres (5.9 in) long. Their scary appearance is purely a ruse; the spines, though prickly, do not sting, and the larva is harmless and actually one of the more easily handled of the saturniidae.
Just before pupation, the larva expels its gut and changes color from Frankenstein-green
to a more fetching turquoise, the skin of the fully fed creature
stretched shiny and tight. They then crawl down the host plant, where
they burrow into the dirt and pupate
in a well formed chamber at a depth of five to six inches. The pupae
are dark brown/black in color, and have a relatively short cremaster.
Some pupae overwinter for 2 seasons, perhaps as an adaption to variable
and adverse conditions such as fires and flooding, or to maintain
genetic diversity across generations.

| Regal Moth |
When the moths eclose, they have to pump their wings with fluid to extend them. The females emit pheromones, which the male can detect through its large, plumose antennae.
Males can fly for miles in order to reach a female. After the moths
mate, the female spends the majority of the remainder of her life laying eggs, while the male may mate several more times. Adults of this family of moths have vestigial mouths, meaning their mouthparts have been reduced. Because of this, they do not eat and only live for about a week as adults.
Needless to say it was a lifer for me and a real treat.
