Cryptocephalus biguttatus

Confusion species: Cryptocephalus bipunctatus


Status: Rare, listed as RDB2 'Vulnerable'

Other notes: Very similar to C. bipunctatus var. thomsoni and requires close examination to separate them. Historically, a number of records of C. biguttatus have been shown to actually be C. bipunctatus var. thomsoni. Easily distinguished from the common form of C. bipunctatus. See Mann & Barclay (2009) and the correction on p.38 of The Coleopterist 19(1) (2010) for more on this.
