Overwintering leafhopper adults are now active in vineyards, especially on earlier varieties, and can be found on developing shoots and leaves in the vine canopy. Virginia Creeper leafhopper (VCLH) egg deposition has already been observed at sites in both Mendocino and Lake counties. No eggs of the western grape leafhopper (WGLH) have been found yet.
Fig. 1 VCLH egg deposition has been observed as early as April 5 in both Mendocino (1A) and Lake (1B) counties. No WGLH eggs have been found yet.
