ON THE USE OF AMPULLATE GLAND SILKS BY WOLF SPIDERS (ARANEAE, LYCOSIDAE) FOR ATTACHING THE EGG SAC TO THE SPINNERETS AND A PROPOSAL FOR DEFINING NUBBINS AND TARTIPORES
The journal of arachnology
The means by which female wolf spiders attach an egg sac to their spinnerets was investigated using scanning electron microscopy. In four Pardosa species, we observed that silk fibers emerging from ampullate gland spigots had been affixed to the surface of the egg sac. More specifically, primary (1Њ) and secondary (2Њ) major ampullate (MaA) glands and 1Њ and 2Њ minor ampullate (MiA) glands all contributed fibers for this purpose. The diameters of the 2Њ MaA and 2Њ MiA fibers were greater thandoi:10.1636/0161-8202(2003)031[0209:otuoag]2.0.co;2 fatcat:6n4gd2ablzfzxjfxllpd2twtnq
