Containing group: Sarginae


Many species of Merosargus are metallic blue or green (James 1981). Merosargus adults are sometimes collected in aggregations around rotten fruit. Almost all Merosargus species are native to the Americas south of the USA. M. caeruleifrons is found in Eastern US to Texas, and M. beameri ranges as far north as Arizona (Woodley 2001).


Merosargus is distinguished from other Nearctic Sarginae by the bare eyes, the absence of a mesal fingerlike projection of the pedicel into the flagellum, and the absence of a distal projection on the lower calypter (James 1981).

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
