True Bug
Small "true" bug, about 4-5mm
The tip of the forewing of Heteroptera is fairly thick (~1.2 microns), thus there is no color iridescence visible (brown curve). The base is even thicker and leathary. This is the origin of the name "hemiptera" which means "half-winged". The newer name Heteroptera means also "mixed-wings". This leads to the typical "X" structure of the closed wings in dorsal view, which is an easy means to identify "true" bugs.
Hind wings in contrast, are much thinner (~0.2 microns here), which leads to a brillant blue-violett if illuminated coaxially.
