It is encouraging to learn of many Monarch butterfly sightings. I saw one during a bike ride through ag fields yesterday and got reports of another south of my place. We released six more today from our rearing efforts and tagged three of them. We are at 110 released and have about fifty chryslids to eclose yet.

If you see a Monarch in the next month, take a look on its rear wing to see if there is a 1 cm diameter white tag there, try to read the number (binoculars needed). I would love to know where our tags travel. Our series of numbers is XAA025 thru XAA074. 

Today, Alison and I walked our milkweed field for a survey of caterpillars and chrysalids. We were at it for an hour and forty minutes and were pleased to find 55 caterpillars and nine chrysalids. We also scared up seven fresh Monarch butterflies (nice color and had difficulty flying and were away from where we put the released ones.) Most of the caterpillars were in the 4th or 5th instar (large) and one had attached to a milkweed plant, ready to pupate.

Looking for caterpillars is easier now that they are so big. We left all the caterpillars in the field because at this size they have a good chance of successfully developing into a butterfly. 

Please, if you have time search the milkweed near you and report your results (positive or negative) to Mission-monarch.org.  If you are interested in what others have found, you can look at the data deposited there.
