The venom apparatus of a female C. congregata observed in confocal microscopy imaging. A: Observation of nuclei using a 330–380 nm filter after DAPI staining; B: observation of chitin and actin-associated molecules using a 465–495 nm filter after FITC staining; C: merged picture of A and B. D-F: The venom gland at higher magnification. OV, Ovipositor; VG, venom gland; VR, venom reservoir. Pictures were taken using the 4x objective (A-C) or the 60x objective (D-F) of the confocal microscope
