Came across a Florida Predatory Stink Bug (Euthyrhynchus floridanus) attacking a Spotted Lanternfly (Lycorma delicatula).

First Adult Spotted Lanternfly (Lycorma delicatula) observation of the year

Last year, I made my first adult Lycorma delicatula observation on 6 July 2025. This year, it was 8 days later (14 July 2026). A large stand of mature Tree-of-Heaven (Ailanthus altissima) were cut down in mid- and late June. These trees were were many of the egg masses from the fall were observed and they made for good observation points. 

This observation was on a young Tree-of-Heaven.

With the large number of (visible) egg masses in my neighborhood in the fall and the large number of black and red nymphs, I fear it will be another booming year. 

In 2025, I made 1,519 observations in Arlington, Virginia.

First Spotted Lanternfly (Lycorma delicatula) observation of the year

 

Last year, I made my first Lycorma delicatula observation on 13 April 2025. This year, it was 10 days earlier (3 April 2025) in nearly the same spot. With the large number of (visible) egg masses in my neighborhood, I fear it will be another booming year. 

In 2025, I made 1,519 observations in Arlington, Virginia.
