Adults have been recorded on wing from April to October.
The larvae are aquatic and have been recorded feeding on Lobelia dortmanna, Isoetes tuckermani and Isoetes muricata. They have a yellow head. Full-grown larvae reach a length of 11 mm. The larvae have been recorded from August to mid-November. The species overwinters in the larval stage. Pupation takes place in a cocoon, which is spun on a leaf at the base of the rosette.[3]
