Blue Dasher

Friday 29 November 2013

The Blue Dasher (Pachydiplax longipennis) is a dragonfly of the skimmer family. It is common and widely distributed in the United States. Mature males develop a bluish-white pruinescence on the back of the abdomen and, in western individuals, on the thorax. They display this pruinescence to other males as a threat while defending territories at the edge of the water. Although the species name longipennis means "long wings", the wings are not substantially longer than those of related species. Females do, however, have a short abdomen that makes the wings appear longer in comparison.

Millipede

Wednesday 16 October 2013

Millipedes are myriapods that have two pairs of legs on most body segments. Each double-legged segment is a result of two single segments fused together as one. Most millipedes have very elongated cylindrical bodies, although some are flattened dorso-ventrally, while pill millipedes are shorter and can roll into a ball, like a pillbug. The name "millipede" is a compound word formed from the Latin roots mille ("thousand") and pes ("foot"). Despite their name, no known millipede has 1,000 legs, although the rare species Illacme plenipes has up to 750. Common species have between 36 and 400 legs. The class contains over 12,000 named species in 16 orders and 147 families. The giant African millipede (Archispirostreptus gigas), is the largest species of millipede.
