Welcome Monarch Butterflies!

27 Aug

The 2022 migration has begun!

In late August, masses of these butterflies begin an epic trip stretching thousands of miles from areas across the United States and as far north as Canada to overwinter in mountaintops of Central Mexico.

On their way south, the amazing Monarchs pass through CV to eat our native milkweeds.

A typical Monarch travels for 30-45 days. This year, the migration is expected to pass through our area from @ Aug 23, 2022 until @ Sept 15, 2022, peaking, roughly, during the first weeks of September.

They won’t hang around long. Monarchs will travel as much as 2,100 miles, averaging 50 miles a day, to reach their destination in Central Mexico by the end of October.

Resting in the treetops, the butterflies hibernate for four months, covering oyamel fir trees (Abies religiosa) in thick layers that resemble black and orange leaves. During this period, the monarchs sit with wings folded, living off of fat reserves, until they head north in the Spring.

Want to Help Catch and Raise Butterflies Here at CV?

On nice days, we will aim to be outside at 1pm and around 4-6pm. Any grownup residents (and their kids, if they have them) can learn to help safely catch and tag the butterflies. (Watch this video from min 5 to 7 to see how to net and handle the creatures.) To get involved and learn more about when we plan to be outside, please send an email message to cvearthlab@gmail.com. We keep the pro-grade nets locked in the shed and limit shed access to active garden members (its never too late to join!)

Collecting Caterpillars to Raise

Monarch butterflies only lay eggs on milkweed, so any caterpillars found on the pink and white flowered plants are baby Monarch butterflies. We can raise these in the net habitats. — if you find one please alert the group (cvearthlab@gmail.com) and put it into the habitat with some milkweed. Its best to keep the caterpillar outside and avoid touching it (our germs can hurt them.) After a week or two , it will turn into a crysalys, transforming after 7-10 days, then emerge as a butterfly.
