Gram-negative rods. Motile by peritrichous flagella.
Facultatively anaerobic, growth temperature 37 ºC. Highly motile, resulting a thin film
of bacteria on the agar surface (swarming). S-type, non-pigmented colonies on
swarming inhibitory media.

Isolated only from living and dead gypsy moth larvae (Porthetria dispar L.).
The role in the production of disease in gypsy moth larvae has not been established.
