Lysiphlebus testaceipes is a species of small braconid parasitoid wasp in the subfamily Aphidiinae.

[7] The ability of this species to spread into cooler areas led to its removal from the European Plant Protection Organization's list of positive biological control agents in 2008.

When the larva has finished feeding after 6 to 8 days, it kills the aphid, leaving the skin as a protective hardened shell, or mummy.

L. testaceipes has a notably wide host range, exceeding 100 aphid species in several genera.

[4] Hosts include Aphis craccivora, Schizaphis graminum, Melanaphis sacchari and Myzus persicae.
