No. IV.-EMBIIDINA UND NEUROPTERA (CONIOPTERYGIDAE UND HEMEROBIIDAE).

Jumping mechanisms in lacewings (Neuroptera, Chrysopidae and Hemerobiidae).

Lacewings launch themselves into the air by simultaneous propulsive movements of the middle and hind legs as revealed in video images captured at a rate of 1000 s(-1). These movements were powered largely by thoracic trochanteral depressor muscles but did not start from a particular preset position of these legs. Ridges on the lateral sides of the meso- and metathorax fluoresced bright blue whe...

Sperm ultrastructure and spermiogenesis of Coniopterygidae (Neuroptera, Insecta).

The spermiogenesis and the sperm ultrastructure of several species of Coniopterygidae have been examined. The spermatozoa consist of a three-layered acrosome, an elongated elliptical nucleus, a long flagellum provided with a 9+9+3 axoneme and two mitochondrial derivatives. No accessory bodies were observed. The axoneme exhibits accessory microtubules provided with 13, rather than 16, protofilam...
