Elipsocus hyalinus
(Stephens, 1836)
Elipsocus hyalinus is a of barklouse in the Elipsocidae, characterized by yellowish-black coloration. It is widely distributed across Europe, with additional records from North America, North Africa, and parts of Asia. The species feeds on diverse plant material including fruits, berries, and foliage of numerous tree and shrub species.

Identification
Distinguished from similar Elipsocus by coloration and genitalia characteristics; precise identification requires microscopic examination of wing venation and male parameres. The yellowish-black color pattern separates it from some , though reliable determination typically requires taxonomic keys.

Europe: Great Britain, Ireland, Austria, Belgium, Cyprus, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland; also recorded from Czechoslovakia, Yugoslavia, USSR (historical). North Africa: Algeria, Morocco, Israel. North America: USA. Asia: Mongolia.
Diet
Feeds on fruits and berries including horse chestnut (Aesculus hippocastanum), plum (Prunus), rowan (Sorbus aucuparia), snowberry (Symphoricarpos), and wayfaring tree (Viburnum ). Also consumes foliage from trees: alder (Alnus), ash (Fraxinus), beech (Fagus), birch (Betula), blackthorn (Prunus spinosa), broom (Cytisus), Chinese juniper (Juniperus chinensis), elder (Sambucus), hawthorn (Crataegus), hazel (Corylus), ivy (Hedera), juniper (Juniperus), larch (Larix), oak (Quercus), pine (Pinus), sycamore (Acer pseudoplatanus), sea buckthorn (Hippophae), spruce (Picea), turkey oak (Quercus cerris), and willow (Salix).
Ecological Role
and phytophage contributing to nutrient cycling in forest and shrubland . Feeding on surface material of plants places it within the guild of micro-decomposers and surface-feeding psocopterans.
Human Relevance
No documented economic or medical significance. Occasionally encountered in entomological surveys and biodiversity assessments.
Similar Taxa
- Other Elipsocus species share similar body plan and preferences; require examination of genitalia and wing venation for definitive separation.
- Other Elipsocidae members occupy similar on vegetation; identification to level requires knowledge of psocopteran .

Taxonomic Note
The was described by Stephens in 1836. The Elipsocidae is placed in the infraorder Homilopsocidea within Psocomorpha. The Elipsocus contains multiple species with overlapping distributions in Europe, necessitating careful morphological examination for accurate identification.
Feeding Ecology
The broad dietary breadth across diverse angiosperm and gymnosperm suggests a feeding strategy rather than specialized host associations. This dietary flexibility likely contributes to its wide geographic distribution.
