Monstro the Cat

Today my Lunas have reached their 4th instar i think? the big differences are their heads and butts have gotten larger and darkened as seen below:

Also a cute cecropia on a leaf this is day 15 for this little cecropia:
And I wanted to get a comparison on my 2 largest caterpillars. They are only a day apart and my luna is gargantuan! I named him monstro. The cecropia only hatched the day after my lunas but cecropias are supposed to be much larger in general. so either i have massive lunas, midget cecropias or my cecropias are going to explode before they pupate.
Also a luna cast skin:
And here is my plant setup. I collect plants and keep em fresh for up to a week and a half in water-filled orange cream soda bottles on my window sill.
Today at work at the field museum I sorted Scarabidae beetles into their localities and then by subfamily:
Gymnetis (genus) a.k.a. Harlequin Flower Beetle:
melolonthinae (subfamily) a.k.a. may beetles or june bugs:
