Parthenolecanium quercifex
species of insect
Parthenolecanium quercifex, the oak lecanium scale, is a species of soft scale insect belonging to the family Coccidae within the order Hemiptera.
Etymology
The scientific name, Parthenolecanium quercifex, refers to the oak tree (Quercus) as its primary host.
Description
Adult females have a hemispherical shape and measure 4–7 mm in length and 3–5 mm in width. They exhibit color variations of light to dark brown/gray, often featuring lateral humps on their back.
The insect closely resembles other scale species, leading to uncertainty about its identity and the possible existence of a cryptic species complex.
Distribution and habitat
The species is prevalent in the eastern United States. It primarily infests oak trees but has been observed on other species, such as hickory and birch.
Ecology
The oak lecanium scale undergoes one annual generation. Egg laying occurs in late May to June, and hatching takes place in June to early July. The egg count varies, influenced by multiple factors, with reports ranging from dozens to thousands per female.

Why this record matters
“Parthenolecanium quercifex” is worth following because a concise public description often conceals a longer documentary argument. Here, Parthenolecanium, quercifex and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 16, 2024. The linked authority identifier is Q10621342. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
