This datasheet represents an Approved Method for:
Major Hosts identified in the CAPS Host Matrix*:
*This list includes important economic or environmental hosts but does not represent all major hosts of the pest. Check CPHST pest datasheet for complete list of hosts.
Human and Animal Pathogens Transmitted:
Not known to transmit any human or animal pathogens.
Plant Pathogens and Organisms Vectored:
Not known to vector any pathogens or other associated organisms. Sooty mold can develop on honeydew produced by L. delicatula, leading to disrupted photosynthesis. This can cause reduced tree growth, death of seedlings, as well as a decline in the quality and yield of grapes.

3031 - General Visual Observation
03/22/2018: There is currently no approved trap or lure for this species. Visual survey is considered the most effective method of detection for SLF. Field trials testing the efficacy of brown, sticky tree bands and a methyl salicylate (high-release) lure are ongoing. The band and lure combination are in use as part of the spotted lanternfly emergency response program in Pennsylvania and states with recent detections. The band and lure combination will be considered for inclusion as a CAPS approved method for pest surveillance based on the outcome of field trials and observations from the SLF program.
The approved method for negative data reporting is visual inspection. Note that surveying for egg masses only, for instance when conducting gypsy moth surveys, is not sufficient for negative data reporting. Negative data may be reported if fourth instar nymphs or adults are not found and no feeding damage symptoms are observed when host material is inspected between July and November.
Lycorma delicatula is very distinctive. The first three instars are black with white spots and the fourth and final instar is red with white spots and red wing pads.
This species is large and striking in appearance. It is not likely to be confused with other species found in the United States.
