Macrolophus pygmaeus is a species of plant bug in the family Miridae.

[1] This species is omnivorous, preying on Tuta absoluta eggs and larvae,[5] Ephestia kuehniella eggs, Macrosiphum euphorbiae nymphs,[6] and plants such as Vicia fava.

[7] Its varied diet has created interest in M. pygmaeus as a pest control insect for the prior mentioned species.

Males use vibrational communication in their courtship process, actively walking down the host plant until a female is found.

Macrolophus pygmaeus males produce a vibrational sound called a “yelp” that is associated with male-male interactions.
