Earlier this week, toward the end of the vacation my husband and I took to the island country of Bermuda, I remembered to ask my sister-in-law who was staying with our boys how the monarch eggs that I charged with her care were doing. I did not get a response.
Our cell phone service on Bermuda was nil, and I only used the “free” wi-fi at our resort, so the occasional text I sent might have been missed or not even received. I worried more about how my sister-in-law would feel about some of the eggs not hatching or the caterpillars not surviving than about whether there would still be ten tiny representatives of the monarch life cycle upon my return.
Monarch eggs, the first stage of the monarch life cycle, hatch in anywhere from 1-4 days after being laid by an adult female monarch on a milkweed leaf, depending on conditions. I had found the eggs approximately three days before we left on our trip. I laid out all the leaves and showed my inexperienced, yet willing, monarch conservation participant what they looked like. We discussed what they do when they hatch – eat their egg shells, and then start eating a lot of milkweed. I told her that the caterpillars will be so tiny they will look like a whitish string on the leaf, encouraging the important tool of daily observation when rearing monarchs. The string is a caterpillar, without stripes. The stripes appear in several days, as the caterpillar eats milkweed and starts to grow.
My boys have helped me to rear monarchs for the last thirteen summers. They could manage the monarch care, if my sister-in-law felt unsure or things started to go awry. Yet, when my question went unanswered, I wondered if it was because I had bad news awaiting me upon our return from vacation.
I would find out soon enough, so I did not ask again. The day arrived yesterday. We arrived home and after initial hugs, updates, and animated conversations about all our international wait staff on the island, I asked again about the monarch eggs.
“Did any hatch? Do we have any caterpillars?” I asked.
My answer was a firm yes! We have nine caterpillars! Only one egg did not hatch. Wow! I was so impressed! Last year, I found most of the monarchs I raised in the caterpillar stage. Of the three eggs I found, only one did not hatch. So I was hoping to have a better percentage of success than 66%. Ninety percent was excellent! I was really pleased and thanked my sister-in-law and our boys for taking such good care of our tiny charges.
After dinner, I needed to refresh the milkweed the caterpillars were eating. When they are very small, I empty the entire contents of the netted growing container leaf by leaf on to the counter and make a count. Guess what?! We have TEN, not just nine, Monarch caterpillars. They all are striped now, making them somewhat easier to see, but still they like to hide in the curled edge of the drying leaves. TEN! Ten means 100% of our eggs hatched! Wow! I am so thankful!
After counting and cleaning, which only entails getting rid of old, dried leaves, and dumping the frass (poop), new milkweed leaves were supplied, along with a slight misting of unsoftened water (something I used to do regularly, but found it is not absolutely necessary to do).
When arriving at my milkweed patch in my garden, I was greeted by a monarch flying from plant to plant! What a welcome sight! I picked some fresh leaves to place in the growing container and just happened to find three more eggs!
Today, I will order my tags from Monarch Watch, so that when I release these monarchs after they complete their life cycle, they can be tracked, if found. This will be the third year I have participated in tagging the iconic butterfly. It will be a special year, as I will have raised more from eggs than ever before!
Thanks, Aunt Mary, for taking such good care of your tiniest charges! (And the big, human ones, too!)
