Identification
Eucalyptolyma can be distinguished from other Aphalaridae by their association with Eucalyptus and specific genitalic characters used in species-level identification. are small (2-4 mm), with membranous wings held roof-like over the body. Nymphs produce characteristic —protective coverings—on Eucalyptus leaves, which can aid in genus-level detection.
