  Yellow Striped Armyworm This is the same caterpillar showing the different color configurations between different instars. The one on the top left shows red lines on the lower side while the on one on the right did not have those lines. The yellow stripe is still visible on each one, along with the black eye spot in the third segment behind the head. The one on the left has more of a brown for the basic color while the one on the right is black.

Cabbage White Butterfly
The picture on the right was taken shortly after the caterpillar had emerged from the egg. The picture on the bottom was the day before the caterpillar formed the chrysalis. There will be more data and pictures on the caterpillar page for this individual when I get to it, including pictures of the chrysalis and the butterfly that emerged. |
 
Cross Striped Caterpillar The picture on the left is the same caterpillar as the one on the right, just at earlier instars. you will notice the two individuals on the left look different from each other. The one on the right is the earlier instar while the one on the left has enter the next instar. You can just see the beginning of the cross stripe pattern in the individual on the left. The caterpillar in the picture on the right is a mature, or nearly mature caterpillar and should for a pupae soon. |
 Pipevine
SwallowtailThis is the caterpillar for the Pipevine Swallowtail butterfly. I found him crawling across the back yard and thought it would be nice to keep him until he transformed into the butterfly. Unfortunately I have no pipevine in the yard and could not find anything he would eat. I considered that he may be getting ready to form his chrysalis so I kept him overnight. The next morning he was still crawling around so I set him loose. Hopefully next year I will have pipevine in the yard and can acctract more of the butterflies. |
 
Eastern Tiger Swallowtail This is the mature caterpillar for the Eastern Tiger Swallowtail Butterfly. By mature I mean that the next step is the chrysalis. There are more pictures coming, including pictures of the chrysalis. |
 
Unidentified Caterpillars found on Boston Fern. This appears to be two different color variations of the same caterpillar. The same pattern that is on the back of the green caterpillar is visible in the black back of the other caterpillar. One black has gone into pupae and a second one appears ready to enter pupae. The green one is still happily munching on fern leaves. |

The
bottom picture
is of the last
instar
before the
caterpillar goes
into the pupae
stage. You will
notice a totally
different look
on the back and
sides, most
prominent are
the black
triangles.
The
Picture on the
left is the egg
of the Cabbage
White
caterpillar.
This was taken
within a half
hour of it being
laid as I was
watching the
butterfly when
it was laying
eggs. The egg is
about the size
of the point of
a pin, very
small. The egg
looked like a
speck of dust on
the cabbage
leaf, and if you
don't know what
they look like
you will miss
them.
