In the greenhouse, survival of adult green lacewing, Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), was reduced after feeding on flowers from plants treated with a soil application of imidacloprid (Marathon 1% G, label rate and twice label rate). Percent survival for C. carnea at 10 d was statistically different between treatments and controls: 79% for untreated flowers, 14% for label r...

The green lacewings (Chrysopidae) belong to the Order Neuroptera and are described as voracious predators in the larval stage and sometimes also in their adulthood. They are an important group used in integrated biological control in field and horticultural crops. Individuals of Chrysoperla externa were collected during 2007 until March 2008 in five different locations in Jaboticabal, SP, with ...

A new technique is presented that allows mounting insects directly from alcohol storage, while still wet or soaked, without any chemical treatment. It works particularly well for many groups of Hymenoptera, but not with delicate or soft specimens. Preliminary results are also commented for some Coleoptera, Diptera, Hemiptera, Mantodea, Neuroptera, and Orthoptera. External drying is performed wi...

New species of lance lacewings, Spilosmylus spilopteryxsp. n. and Spilosmylus tephrodestigmasp. n., are described from the Philippines and compared with congeners. Both species are characterised by a distinctive wing pattern, which in the case of Spilosmylus spilopteryxsp. n. is relatively spectacular among lacewings. An identification key to the species of Spilosmylus Kolbe known from the Phil...

The third instar larva of Gepus gibbosus Hölzel, 1968 are described and figured for the first time using light and scanning electron microscopy. The females were collected from Derik, Mardin Province, Turkey and maintained in the laboratory. The morphology of different parts of the larva such as head, mandibles, and antennae are described and illustrated. G. gibbosus is new for the Turkish fauna.

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...

A review of genus Bullanga Navás, 1917 is presented. All three species of Bullanga are redescribed and illustrated in detail. The female of Bullanga florida is described for the first time. A key to Bullanga species is also provided.
