Picture of the Month

Pygidial glands

"Pygidial glands", a grape sack-like microscopic structure in abdomens of all beetles of the family Carabidae, which the insects use to produce and store biochemicals for defensive purposes. The gland secretory lobes (yellow) are connected with collecting duct (blue). The beetle’s defensive chemicals are thought to be synthesized in the spherical grand acini (small nodules in secretory lobes) and funneled into the lumina of resilin-rich collecting ducts (blue) for storage and later expulsion from the body. This is the first known case of resilin presence in the glandular system of an insect. The fluorescence is autofluorescence from resilin and dapi counter-stain.  Microscope: Olympus FV10i, obj 10x. Imaged by Adam Rork (graduate student in the laboratory of Dr. Tanya Renner) and Dr. István Mikó in the Department of Entomology.
