Casebearer pupa - Exema
Nashua, Hillsborough County, New Hampshire, USA
August 12, 2007
Size: about 5 mm
Collected with sweepnet from any of a number of herbaceous flowering plants. I placed it on a sprig of goldenrod in a bottle of water, placing some aluminum foil closely around the stem to prevent the larva from dropping into the water. Two weeks later, noting that the larva was no longer crawling around, I decided to remove it from the goldenrod and examine it. The case was glued tightly to the plant. I suspected the larva had pupated inside and was determined to find out. Here is what the once-opening of the case looked like when I detatched it.
