vg is a homozygous lethal mutation killing embryos prior to formation of the syncitial blastoderm. In heterozygous condition it causes duplications of the posterior wing, ranging from very small duplications of the axillary cord and alar lobe to large duplications including much of the wing blade and the posterior row of bristles.

Species diversity and seasonal abundance of muscoid flies (Diptera: Muscidae) developing in biosolid cake (dewatered biosolids) stored at a wastewater treatment facility in northeastern Kansas were evaluated. Emergence traps were deployed 19 May through 20 October 2009 (22 wk) and 27 May through 18 November 2010 (25 wk). In total, 11,349 muscoid flies were collected emerging from the biosolid c...

Popularly known as horse flies or deer flies, Tabanidae, has 4.400 described species distributed worldwide. Most of the females are hematophagous, but several also flower visitors. Cretaceous fossils Tabanidae scarce and fossil have plesiomorphic features unknown in modern flies. Here, we revised taxonomy from Crato Formation Brazil describing a new genus, Araripus gen. nov ., two – crassitibia...
