Antenna: Black, flattened, knife-like (serrate). Segment 2 extremely short, barely visible. 11 segments on both male and female.
Thorax (Pronotum): Triangular, front extended, more rounded at tip. Center has wide black stripe, slightly narrowing at front (base) and extending fully across hind border. Outside edge beyond black border usually yellow, with a very small rose to reddish blotch inward from the yellow. Sometimes the yellow border is entirely black.
Wings (Elytra): Dull black, rough (coarsely punctured) no ridges.
Abdomen: Black, narrow. Last 4 segments of the male dark brownish-yellow on underside; tip lobed. Non-flashing.
Similar Species: Similar to Lucidota atra, but much smaller, thorax blacker.
Size: 5.5 to 6 mm.
Habitat: Wet forests and meadows. Usually near water.
Flight time: June
Life Cycle: Day-flying, without light organs. Adults ‘bleed’ fluid from abdomen sides and legs if disturbed. Life-cycle unknown. Larvae probably feed on smaller insects as other Lucidota species.
Comments: Essex County – listed on Ojibway species list for 2005, but not 2008. However, 10 specimens were found by Luk, et al. from collecting by malaise traps in Essex & Kent counties. No exact locations given.
