Figure 3. X in Megachile (Megachile) montivaga (Hymenoptera: Megachilidae) nesting in live thistle (Asteraceae: Cirsium)
Figure 3. X-ray of three/four nest stems. Nest entrances appeared as darker patches along the stem and larvae at various stages of development were revealed. The small ovals embedded in the pith are fly pupae, reared and identified as Scathophagidae sp.; they appear to be phytophagous and unassociated with the bees. The height of each number is 1 cm.
