The Macroveliidae are a family of bugs within the suborder Gerromorpha .

features

The bugs are 2.5 to 5.6 millimeters long and are similar to some species of the water stripper (Mesoveliidae). They have micro and macro hair, but this only extends to the first abdominal segment. In macropter (fully winged) species of the genus Macrovelia , point eyes ( ocelli ) are formed, they are absent in the other species of the family. The antennae are flagellate and have elongated first and second segments. The third is about 2.5 times longer than the fourth. The labium extends to about the hips ( coxes ) of the middle legs. In the Macrovelia genus, the pronotum is elongated at the back and covers the receding scutellum , the meso- and metanotum. In the other species apteren (wingless) it is truncated. The tarsi are tripartite, the pretarsus is turned apically. The pygophore (the extension of the ninth abdomen segment in males) is located apically on the abdomen. The ovipositor of the genus Macrovelia is similar to that of the dwarf sandpiper (Hebridae), but is located at the tip of the abdomen.

Occurrence and way of life

The family is spread around the world. Chepuvelia usingeri lives in the moist soil litter of forests. All copies were previously known by screening and Berlesetrichter caught. The other two species colonize springs or seepage water areas with heavy vegetation. They are shy of light and often hide in shady areas. Macrovelia hornii overwinters as an imago and can also be active in winter on warmer days. The eggs of Macrovelia are glued lengthways to the substrate by the females.

Taxonomy and systematics

The family includes the following genera and species:
