Macrocentrus marginator
(Nees, 1811)
Macrocentrus marginator is a of in the Braconidae, a large group of wasps that develop as parasitoids of other insects. The species was first described by Christian Gottfried Daniel Nees von Esenbeck in 1811. Records indicate presence in Scandinavia, specifically Denmark, Norway, and Sweden. As a member of Macrocentrus, it likely functions as a larval parasitoid, though specific associations for this species remain poorly documented.

Identification
Distinguishing Macrocentrus marginator from other Macrocentrus requires examination of morphological characters such as wing venation, segment count, and body proportions. Species-level identification in this typically depends on detailed examination of the ovipositor, propodeum , and coloration patterns. Reference to specialized taxonomic keys for European Braconidae is necessary for reliable identification.

Distribution
Recorded from Denmark, Norway, and Sweden. The limited distribution records suggest a European, possibly boreonemoral or hemiboreal range, though sampling may affect this pattern.
Ecological Role
As a member of Braconidae, functions as a , contributing to of insects. The specific ecological role of this is undocumented.
