It looks like a june bug pupa.

Definitely not a Junebug pupae. It's the pupae of one of the Sphinx moths. Many of the species have very similar pupal cases so it's almost impossible to tell who is who until the moths emerge.

The loop on the left side is rather odd. Is it perhaps the tongue structure for a big moth?

Sphinx moth pupa is much better than junebug! (pupae is plural pupa is singular)

Yes, the handle holds the developing mouthparts. Sphinx moths are fairly good sized insects, but there are other species much larger that don't have that appendage. They do, however, have an extremely long proboscis, which consists of two parts connected to form a tube. That's the reason for the hook.....neat, huh?

That is what a hornworm looks like when it goes into the soil to later emerge as a moth.

hummingbird moths. we have these. they are fun to watch at dusk. they look like chubby short hummingbirds and aren't the least bit afraid of humans. they buzz around from flower to flower. the kids LOVE watching them! they like pentas and lantana as well as my duranta bush.

it's remarkable how much they resemble the hummingbirds. we thought they were fat baby hummingbirds the first time we saw 3 of them flitting around at dusk. it's hard to tell because of the time of day/night that they appear. it's like clockwork, however

Marvelous photo !
