Gram-negative, straight rods, 0.5-0.8 x 0.9-2.0 μm, non-sporulated. Some strains are
capsulated. Motile by peritrichous flagella.
capsulated. Motile by peritrichous flagella.
Colonies are 1 to 3 mm in diameter, circular, shiny, opaque, cream-white and smooth
with an entire margin. Facultatively anaerobic, growth temperature 20-35 ºC (range
may vary from 10 to 40 ºC). Don't require growth factors. Media: Nutrient Agar or
Nutrient Broth, Trypticase Soy Agar ± 5% sheep blood, Mac Conkey Agar, Milk Agar.

Isolated from larvae of Costelytra zealandica (grass grub) with amber disease, and from the environment.
S. entomophila and S. proteamaculans cause amber disease (amber coloration) in the grass grub Costelytra zealandica
(Scarabaeidae). Infection turns the grubs a honey or amber color. Pathogenic strains of S. entomophila colonize the larva gut, adhere
to the crop, and induce starvation, which causes depletion of the fat bodies. Pathogenicity is correlated with the production of
lecithinase, proteinase, and chitinase.
