A Giant Swallowtail egg.
An egg ready to hatch. Note the head of the
caterpillar showing through the shell.

A caterpillar has just molted. It's old skin
is directly behind the caterpillar.
A Giant Swallowtail caterpillar eats Wild Lime.
The actual head of the caterpillar is seen best
when photographed directly from the front.
A caterpillar extends its osmeterium, a forked gland
which it extends when disturbed.
The osmeterium exudes a fluid
which is considered to smell horrible.
The color of the osmeterium of each swallowtail
species is different.
Giant Swallowtail osmeterium is bright orange-red.
A Giant Swallowtail attaches itself in
a crescent shape to prepare for pupation.
Along with the normal silk pad a caterpillar uses
to attach its back prolegs,
note the silk 'girdle' or 'sling' the caterpillar makes and uses to hold itself in place.
To become a chrysalis, it simply wiggles
out of its skin. This time the skin
did not fall free but remained attached
at the rear of the chrysalis.
This simply looks like
the broken tip of two branches.
When the full photo is shown, the method
of camoflauge is clear. A Giant Swallowtail
chrysalis looks like a broken branch.
Note the spiracles on the side of the chrysalis.
A Giant Swallowtail female pupa (chrysalis) is indicated by the line between the two red arrows in the enlarged photo (click on photo).
A Giant Swallowtail male pupa (chrysalis) is indicated by the dot at the tip of the red arrow in the enlarged photo (click on photo).
While photographing eggs through the microscope,
this egg appeared dark all over.
It should have been dark only where the caterpillar head would show.
As I continued to photograph the egg, I noticed
little 'bugs' crawling out of the egg.
Flipping the leaf to photograph the bugs
crawling out of the egg, I dented the top of the egg.
Using a razor blade, I cut one egg which was
dark all over and found these
immature Trichogramma Wasps developing.
