No egg diapause. Two generations per year.
Season:
Overwinters as late instars with first adults singing as early as December. Second generation numbers are greater with adult males heard in early summer.
Name derivation:
"line" = "line", "ceps" = "head" or "lines on the head"; perhaps indicating how the lost holotype appeared.
