Overwintering Monarchs
Eastern Monarch Population
Monitor Overwintering Monarchs in Southeastern U.S.
If you live in the Gulf states of Texas, Louisiana, Mississippi, Alabama, and Florida as well as Georgia, South Carolina and North Carolina, please continue to report monarch observations. We want to hear from you.
The cold temperature that blanketed much of central and eastern U.S. impacted plants. How did the winter storm blast impact monarchs? We only had a handful of observational reports to provide some answers.
Mary in Corpus Christi, TX: “There was one adult feeding on the milkweed plants in the backyard. We lost a lot of our plants in the Christmas freeze, but the milkweed that we had covered up is okay. I doubt if there is much food for Monarch Butterflies in Texas right now.” (01/09/2023)
Larry in Pascagoula, MS: “…Seems to have just transformed into adult and was warming in the sun. Temps in the mid 60s…had a few caterpillars in December, but we had 3 straight days of freezing temps around Christmas and surprised any survived. Very few flowers around so she fed it orange slices.” (01/09/2023)
Jen in Winter Haven, FL: “All for these [8] caterpillars survived 30 degree weathers eggs. Impressive.” (01/03/2023)
