Black spots or patches appear on the elytra, pronotum, or head

Blue, green, or black mold has developed on the surface of fungal blocks or substrate

Decreased activity and loss of appetite may accompany the condition

Dense white powdery mite clusters are visible on the inner walls and lid of the enclosure

In adults, a lymph-like secretion may be observed near the affected area

Larvae come to the walls or surface of the fungal block and refuse to burrow back in

Larval feeding marks (frass tunnels) have decreased significantly

Loss of appetite or reduced activity may be observed

Nematodes are attached to the beetle's body surface, especially between abdominal segments

No egg-laying behavior is observed over an extended period after mating

Numerous thin white or transparent thread-like organisms are visible throughout the substrate

Numerous tiny white mites are attached to the beetle's body, especially around joints and abdominal segments

Part of the pupa turns black with suspected tissue necrosis

Some or all claws or tarsal segments at the tips of the legs are missing

The abdomen appears swollen and distended, suggesting retained eggs

The adult beetle moves restlessly around the enclosure

The adult beetle remains on the substrate surface and moves restlessly without burrowing

The adult beetle remains on the substrate surface rather than burrowing

The affected area appears sunken or is clearly different in color from surrounding cuticle

The beetle cannot climb bark or perches and falls easily

The beetle drags a leg or shows an abnormal gait

The beetle moves continuously due to mite irritation

The beetle refuses food or shows a marked decrease in food consumption

The beetle stops moving mid-eclosion with remnants of the pupal shell still attached

The body appears deformed or the abdomen appears shrunken

The damaged area appears reddened or shows oozing of body fluid immediately after injury

The elytra are twisted or fail to close completely

The female gnaws or digs at the egg-laying log or substrate but does not lay eggs

The hind wings remain exposed outside the body and harden in that position

The substrate emits a fermentation odor (alcohol or sour smell)

The substrate or fungal block emits a foul or putrid odor

The temperature inside the enclosure is elevated due to heat from re-fermentation
