Chionaspis pinifoliae
species of insect
Chionaspis pinifoliae, the pine needle scale insect, is a common species of scale insect found on pine, spruce and other conifers across Canada and throughout the United States. The species is particularly persistent on planted spruce in the Prairie Provinces in both rural and urban settings. In heavy populations, the needles may appear to be flecked with white. The insect overwinters in the egg stage under the white covering of the scale. In Saskatchewan, hatching dates vary from late May to late June. In the Mid-Atlantic region of the United States there can be one or two generations per year and the first generation hatches after an average of 210 growing degree-days. The newly hatched “crawlers” disperse, settle on old or new needles and begin scale development.

Why this record matters
“Chionaspis pinifoliae” is worth following because a concise public description often conceals a longer documentary argument. Here, Chionaspis, pinifoliae and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 3, 2025. The linked authority identifier is Q10450089. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
