Need tree cutting or tree removal in Manhattan & the Bronx?

While the word “weevil” often brings to mind images of pantry pests and garden nibblers, the New York Weevil offers a different story. This large, distinctively patterned beetle is a fascinating piece of NYC’s natural history.

What Makes the New York Weevil Special

  • Size Matters: Reaching 12-18mm in length, it’s a giant in the weevil world.
  • Deceptive Appearance: Those distinctive bristles and light-and-dark patterns provide some camouflage on tree bark, making it easy to miss if you’re not looking for it.
  • Family Ties: While long associated with true weevils, its straight antennae (true weevils have elbowed antennae) placed it in a unique family: Ithyceridae. Modern classifications place it within the broader Brentidae (primitive weevils) family.
  • Local Roots: The “New York” in its name is well-earned as it’s found throughout the eastern US and southern Canada.
  • Tree Connection: It’s associated with trees like oaks, beeches, and hickories, feeding on young leaves, buds, and tender stems.

Observing the New York Weevil in NYC

  • Where to Look: Scan the trunks and lower branches of its favored trees in parks, woodlands, or even larger street trees with rough bark. Spring and early summer are the best times to spot adults, but look closely all year round – they’re surprisingly well-camouflaged!
  • No Need to Fear: They are harmless to humans and generally don’t cause significant damage to healthy trees.
  • Leave it Be: This native species plays a role in our local ecosystem. If you find one, enjoy the observation and leave it undisturbed!
Common Name Scientific Name Notes
White Oak Quercus alba A primary host for New York Weevils
American Beech Fagus grandifolia Another favored host tree
Hickories Carya spp. Various hickory species can be targeted
Butternut Juglans cinerea May be infested, especially young trees
Black Walnut Juglans nigra Less preferred, but possible host

Did You Know?

  • Slow Development: The New York Weevil’s larvae live underground, feeding on tree roots for several years before pupating and becoming adults.
  • Oddball of the Weevil World: It’s a reminder that even within familiar insect groups, there are outliers and unique evolutionary adaptations.

The Importance of Native Insects

Even non-flashy insects like the New York Weevil contribute to the biodiversity and health of NYC’s green spaces. By observing and appreciating these native species, we gain a richer understanding of our urban environment.
