Micromus angulatus (Stephens, 1836) is a common and wide spread species of "Brown Lacewing" (family Hemerobiidae), native to large parts of the Palearctic. It also occurs in North America and it might well be native there too (and hence an original Holarctic species), but it is also possible that it was introduced to the Americas long ago. There is no hard data supporting either theory, so more investigation would be needed.
