B) No visible evidence of feeding damage on ovulate cone scale parenchyma tissue, nor on ovules afer 24 h. C) No visible feeding damage on pollen cone scale parenchyma tissue afer 24 h. D) Pharaxanotha floridana E) More mass (mg) is consumed per surviving beetle from ovulate cone scales than from pollen cone scales over 24 h (p = 0.0033). In A and E, summary boxplots are shown with raw data values overlaid.
