0.5-0.7/1.8-7.0 µm
Vegetative cells are Gram-negative, but sporangia and presporal forms are Gram-positive; non-motile.
Spores: ellipsoidal, central to terminal, thick-rimmed swelling the sporangia, seldom free.

Maximum temperature, 35'C; minimum temperature, 20'C
Growth in anaerobic agar
No growth in nutrient broth or in 2% NaCl
More fastidious nutritionally than P. popilliae
Can be maintained indefinitely by serial transfer in diphasic J-medium (Haynes and
Rhodes, 1963)
No growth at 5.7 pH
On agar medium form small (< 1 mm), yellow-brownish to cream colonies

Spores withstand at least 85 'C
Less widespread than P. popilliae ,
Although sporulation can be evoked by injection of vegetative cells or spores of P. lentimorbus into susceptible grubs, sporulation in
laboratory media has been brought about only by Steinkraus and Tashiro (1955).
Vancomycin sensible.

Infects the larvae of the Japanese beetle (Popillia japonica Newman) and the European chafer (Amphimallon majalis
Razoumowsky); the larvae become milky white because of the prolific production of spores by the bacilli in the hemolymph .
Pure cultures can be isolated most readily from dry films of hemolymph of infected larvae;
Is a weapon for the control and elimination of the Japanese beetle and the European chafer.
