Figure 5

A) Steps to prepare insect specimens for image capturing. B) A special mat target needs to be attached to a scanned specimen for 3DSOM software to estimate of camera viewing position and angle. C) For a large insect such as this 30 mm long Christmas beetle, the pin is glued to a Inline graphic10 mm rare-earth disk magnet which is in turn attached to a Inline graphic50 mm mat target. D) For a small insect such as this 3 mm long granary weevil, the micro pin is glued to a Inline graphic5 mm mat target. E) shows comparison in size of the two specimens.
