Could you post a pic of the eggs? I have lots of monarchs and have gotten a great series of pics running from the caterpillar attaching to a leaf, through the pupa and the hatching into a butterfly, but I don't recognize the eggs. I have lots of butterflyweed, but other insects also lay their eggs there.

I don't have any Monarch eggs (and don't have a camera that could get a good closeup of something that small anyway), but here's a link to some pics showing Monarch eggs. For those in parts of the country that get hot enough to have Queen butterflies, the Queen eggs look similar, so when the little caterpillars hatch out of the eggs, check with a magnifying glass for two pairs of little feelers on Monarch caterpillars or three pairs of feelers on Queen caterpillars.

And here's different stages of the Monarch caterpillars.

Yes will post the photo I took as soon as I can get it developed.....I'm still in the 35-mm age....saving up for a digital right now... :)

I saw a monarch cat today on my A. tuberosa!!! SOOO TINY! :))))

Amy - you know that where there are caterpillars there are no leaves left on the plants. Don't worry. The plants will recover. I cut back my butterfly weeds when the leaves are all eaten. (Right now I have one caterpillar per stem, and I noticed a female Queen checking each stem before she finally landed on a hidden plant that had none.) I did notice that they don't like the cultivated A. tuberosa I have that has yellow flowers. Must have a different taste.

I am not one bit worried. I am EXCITED! When hubby got home I took him out to show him the caterpillar and I found that one again AND a second one on another part of the plant, and that 2nd cat was about 2/3 BIGGER than the 1st cat. They are the coolest :))) I just wish that I was not out of film at the time! I can't wait to see them get bigger & bigger :)

(BTW I ordered my digital camera today!!!)

Well I finally got the pic developed. Can't see the egg's ridges, but it's still a closeup.

Unfortunately, I have not seen a single monarch-cat since the day there were two, one bigger than the other, at about 1" long. :(((((( Every day I wonder where they've gone.
