Explanation of Names
Zygogramma suturalis (Fabricius 1775)
<6.5 mm
Easily distinguished from Calligrapha bidenticola by the form of the tarsal claws or by the color of the epipleuron – characters rarely visible on photos. In dorsal view, C. bidenticola is slightly more elongate than Z. suturalis but otherwise very similar. Do not try to separate the two based on whether or not the elytral stripe is divided. This character varies geographically and is sometimes not even consistent for beetles found together at the same locality. --S.M. Clark, pers.comm. to =v=, 11.ix.2013
