Exochomus quadripustulatus, commonly known as the pine ladybird or pine lady beetle, is a species of beetle of the family Coccinellidae. Exochomus quadripustulatus can reach a length of about 4-6 millimeters. It is almost circular, convex and shining, with a flange around the base. The color is quite variable and may change with age. Usually the elytra are black with two larger red comma-shaped spots and two smaller round red spots. The color of these spots can also be orange or yellow, but completely reddish brown specimens may occur.
This species is present in most of Europe, in the eastern Palearctic, and in the Near East. It was first recorded in Ireland (County Armagh) in 2014. It was introduced to San Francisco between 1915 and 1930 to control the hemlock woolly adelgid, and has since spread across the west coast of North America from California to British Columbia. It is also present in Massachusetts.
This fairly common ladybug can be found from April to October especially on conifers and in areas with deciduous trees. The pine ladybird in both adult and larval stages preys on aphids and scale... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pine Ladybird sighting in Boston on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 967th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pine Ladybird in Boston on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pine Ladybird sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
27th of 27
Of the 27 cities where we can rate Pine Ladybird sightings, Boston ranks 27th at under 5%. The best odds are in Hamburg (Germany, about 10%), Vienna (Austria, about 10%) and Budapest (Hungary, about 10%).

GBIF citizen-science records
It is estimated from how often the Pine Ladybird is recorded against all the insects logged in Boston (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
