Occurrence of Cephaloleichnites strongi (hispine beetle damage on Zingiberopsis, see Wilf et al. 2000). Insect damage census site for Wilf and Labandeira 1999 and Wilf et al. 2001.Total collection size here includes earlier component (for Wilf 2000) without insect damage tally as well as insect damage tally (Wilf and Labandeira 1999, Wilf et. al 2001). See online supplement of Wilf et al. 2001 for insect damage data for each specimen in the insect damage census.
