Common names include yellow poplar weevil, sassafras mining weevil, tuliptree leafminer, tulip tree weevil, or the magnolia leaf miner.
Yellow poplar weevils are small black-snouted beetles and are tick-like in appearance. While in its larval stage, the weevil presents as a white legless grub. Measuring approximately 1⁄16 inch (0.2 cm) long, the adult weevils are normally black or dark brown in coloring.

The weevil goes through a single life-cycle each year. Adults pass the winter months in surrounding leaf litter and become active throughout late April and early May. Before leaf buds on yellow-poplar, sassafras, or magnolia trees open, weevils attack the buds and leave their distinctive feeding... Wikipedia →

With luck
About 10% of wildlife watchers report a Yellow Poplar Weevil sighting in Washington on a given day, based on 503 verified sightings from GBIF citizen-science data. It is the 126th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Yellow Poplar Weevil in Washington on a given day, against under 5% in July to March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Yellow Poplar Weevil sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Yellow Poplar Weevil sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yellow Poplar Weevil is recorded against all the insects logged in Washington (503 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.
