Collected on American Elm (Ulmus americana) leaf. At first, I thought this might be Oberea ulmicola based on the (possible) host plant. The head and antennae are dark (Lingafelter's key suggests the head of O. praelonga is typically lighter?). However, the metepisternum is clearly black (see lateral image) - this would rule out O. ulmicola according to both Lingafelter and Yanega.
