In 3 days ~10% in a week ~20%
Synanthedon exitiosa, the peachtree borer, is a species of moth in the family Sesiidae that is native to North America. The adult female of the species has a wingspan of about 3.5 centimeters. It is dark metallic blue in color with an orange band around the abdomen. It has opaque forewings and clear hindwings. The male is smaller and more slender, and both pairs of wings are clear. The larva is up to 3.5 centimeters long and white with a brown head.
The host plants are trees and shrubs of the genus Prunus, such as peach, cherry, and apricot. The female lays eggs around the base of the trunk, and the larvae bore into it. They feed on the cambium, producing damage so severe that it often kills the tree. Wikipedia →

Rare
Under 5% of wildlife watchers report a Peachtree Borer Moth sighting in Boston on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 830th 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

Among the best
Of the 8 cities where we can rate Peachtree Borer Moth sightings, Boston ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Salt Lake City (United States, under 5%), Denver (United States, under 5%) and Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Peachtree Borer Moth is recorded against all the insects logged in Boston (8 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.
