Researchers studying ambrosia beetles used micro-CT scanning to develop this 3-D reconstruction of the mycangia and other internal organs within the prothorax and mesonotum of an Xylosandrus amputatus beetle. A: lateral side; B: frontal view; C: ventral view; D: mycangium with prothorax musculature nearby. (Image originally published in Li et al 2018, Journal of Insect Science)
