Lintneria istar

Looks almost like a five-spotted hawk moth and range map show that it can be in Arizona, but the white head line is different. Is it a western species or just a variation?

Moved- Lintneria
Moved from
ID Request
.
Something was bothering me about my preliminary ID as
Agrius cingulata
. I am now rather confident that this is a
Lintneria spp.
, of which there are three species in Southern AZ:
L. istar, L. separatus
and
L. smithi
.
I can immediately rule out
L.separatus
as that species is known to have numerous red and orange patches of coloration.
L. smithi
and
L. istar
are more variable and both have darker morphs, similar to this individual. According to Tuttle,
L. smithi
can be distinguished from
L. istar
by orange coloration on the spiracles, while
L. istar
always has entirely black spiracles, like this individual.
The pronounced black area surrounding the first abdominal spiracle is a clear trait of
Lintneria
, as well as the short black caudal horn and the relatively small size overall (as evident by the hand in the picture). The clearest trait of
Lintneria spp.
larvae is the flattened thoracic segments which create an obvious hump. The position of this particular larva and the angle from which it was photographed distorts this trait and thus I didn't immediately recognize this as a
Lintneria sp.

Hawk moth
I think this is the pink spotted hawkmoth (
Agrius cingulata
), which is highly variable in its larval stage.
EDIT: See my above comment
