Hungry Cecropia Caterpillars

The Cecropia Moth Caterpillars in Brookside Gardens’ Wings of Fancy exhibit are very large and I can hear them eating when the area is quiet. They are eating cherry leaves in the Caterpillar House but evidently eat maple and birch leaves as well. They are native to our area; I saw one at Mt. Pleasant Farm back in September 2014.

The moths have one generation a year – overwintering as a cocoon. Like large moths, they don’t eat as adult so the adults live a very short time…laying as eggs. The caterpillars eat until they are large enough then make a cocoon.

The caterpillars at Brookside are provided with so much food that they are making cocoons in July! One got ‘ready’ while I was volunteering in the Caterpillar House. It became desperate to leave the food plant – crawling around the rim of the pot that the cherry branches were in and then falling off into the big tray below. The caterpillar was gently moved to a display cabinet where it made its cocoon on a branch. I didn’t see the making of the cocoon but the next day, it looked like a wad of wilting green leaves and few days later it was brownish. Hopefully the cocoon will overwinter and become a cecropia moth next spring!
