'Wings experience substantial accidental collisions during the life span of a flying insects. Such collisions often result in irreversible wing damage and, therefore, could significantly influence insect flight ability. In order to investigate the material composition of wings of the dragonfly Acisoma panorpoides, I used confocal laser scanning microscopy (CLSM). During the scan, I observed no autofluorescence from wing membrane. This was very odd, because membranes are known for their blue autofluorescence when subject to laser light. Interestingly, after the scan I found out that wing membranes were all broken.'
