Psilogramma Hawk Moth (Sphingidae Sphinginae Psilogramma menephron - Cramer, 1780)

Found the three larvae October 23, 2002 on Oleaceae Ligustrum sinense next to a housing estate on Cheung Sha Wan Road in Sham Shui Po, Hong Kong.  The following week, one larva was found on the same LFP at Choi Sai Woo Park in North Point.  In the last half of December, four more mature larvae were found near Aldrich Garden Estates in Shau Kei Wan.


A mature 2nd (?) instar, Oct 23, 2002.
The larva was 4 cm / 1.6 inches long at this stage.

The 3rd (?) instar stage, Oct 27, 2002; length was 4.4 cm / 1.7 inches
Note the green tail spike; P. increta has a dark brown (or black) spike.
Note the absense of any lateral spotting which is present on P. increta.

The final instar stage,  Oct 27, 2002; length was 6.9 cm / 2.7 inches
Note the green tail spike; P. increta has a dark brown (or black) spike.


A mature larva in a typical rest (or alarm) posture.
 

View of the prepupal larval form.


The pupa was about 5.7 cm / 2.3 inches long.
Pupation of the mature instar above occurred about Oct 29, 2002.
As with P. increta, the pupa was formed underground.
The longer "tongue tube" marks this certainly as a different species from P. increta.

The moth eclosed on Nov 21, 2002.
