decemlineata = 'ten-lined' (refers to elytral pattern)
5.5-11 mm(1)
Ten black stripes and irregular punctures on the pale yellow elytra (regular punctures indicate L. juncta(2)); larva has two rows of black spots on each side (one row in L. juncta)
transcontinental (NS-BC to FL-CA)(3)
Potatoes and related plants(1)
Life Cycle

L. texana vs. L. decemlineata

L. juncta
In the east, L. decemlineata could be confused with L. juncta. In Texas, it could possibly be confused with L. defecta or L. texana, although these species have fewer elytral dark stripes. In Arizona and possibly neighboring areas, it could be easily confused with L. tumamoca. --S.M. Clark, pers.comm. to =v= 25.vii.2014
