The love dart of C. nemoralis has four vanes thickest at base and tapering steadily distally to give a cross section of a simple cross (1:). But, the dart is very brittle and often missing. For examination, a stereoscopic dissecting microscope at c.X20 is needed.
Top images coloured with food dye. Within the dart sac, the dart is encased in mucus. Images are of a dart in water; the mucus case and distal portions of vanes collapsed when taken out and dried; perhaps because the dart was not yet fully calcified.
