Adventures in Caterpillar Care (2)
/My husband handled the feedings while I was in Dallas and Wichita Falls for 3 days; I left him plenty of sweet gum leaves (in the bin and in a vase to be added as needed). He managed although at one point they seemed so hungry that he thought they would run out food. The caterpillars were noticeably bigger with I returned home! I went to get fresh food the next morning…and that is when I started making some changes.
I opted to move the caterpillars to a slightly larger bin with a ruler added to hold the leaves above the coffee filters (and frass that accumulates very quickly). The fresh leaves that the old container held did not last 24 hours! I counted 40+ luna moth caterpillars and at least 3 cecropia moth caterpillars as I moved them on leaves to their new bin. It turned out that the larger bin was not big enough either since the leaves were almost all gone in 24 hours. The bigger caterpillars eat more than the newly hatched ones.
As they passed their 2-week-old mark, I moved the luna moth caterpillars to a large been with a cookie cooling rack to keep the leaves off the bottom. I have a paper towel layer there rather than coffee filters. Sometimes I can stick the twig through the metal grid so that the leaves stand up for easy caterpillar access. When I moved the luna mother caterpillars to the big bin, I counted 50 before I got sidetracked and lost the count! I’ll try to count each time I move them to a clean bin (probably every other day); they like to be under leaves so it is impossible to see most of them just looking down into the bin.
The luna moth caterpillars are now mostly green – which also makes them harder to see! How many do you see in the two pictures below?
When I moved the luna moth caterpillars to the big bin, I gave the cecropia moth caterpillars their own. There are 4 of them. They don’t grow as fast as the luna moths; they seem to like the sweet gum leaves (I tried maple leaves since some references list them as a popular food plant, but these caterpillars were already imprinted on sweet gum so they will continue to get it. The cecropia caterpillars are in the bin that I only used once for the whole group. It should work very well for them until they get very large.
Stay tuned for next week’s post about the continuing adventure.
