Beetles were pollinating plants more than 150 million years ago, before there were bees, butterflies, or flowers. They have never gotten good at it. A beetle cannot drink nectar, flies like a thrown brick, and chews on whatever it lands on.
Week Seven closes the Great Southeast Pollinator Course. Dr. Joe McHugh (UGA Department of Entomology) starts at beetle anatomy and works out to pollination. The elytra, the hardened front wings that give Coleoptera its name, bought beetles armor at the price of clumsy flight, and their antennae read scent and heat rather than color. Then the numbers: 65,000 weevil species against 35 in the entire dog family, 400,000 described beetles against 320,000 plants, one in four described animal species. He names beetle pollination cantharophily, calls beetles “mess and soil” pollinators, and closes on the eight southeastern groups you will meet on a flower. Nitidulids pollinate the pawpaw. About 1 hour 14 minutes; Becky Griffin takes over for census wrap-up at 51:18.
Great Southeast Pollinator Census: August 21–22, 2026. Educators attending live earned 1 PLU. This is the archived recording; no credit or applicator CEU applies.

Questions Answered
Can a beetle drink nectar?
No. Beetles have opposed mandibles that pinch and chew. No tongue, no proboscis. Even a weevil’s long snout ends in small biting jaws.
Should I pick up a blister beetle?
No. Meloids exude cantharidin from the joints of the body and it blisters skin. The bright contrasting pattern is the warning.
Where does a beetle go on the count sheet?
Under “other insects.” The original sheet had no beetle on it, the updated form does, and this year’s “I Counted” sticker features lady beetles in McHugh’s honor.

Platform Note (not part of the pasted description)
The chapter list is kept whole and the prose was condensed instead. All 62 chapters from the Stage 2 archive package appear here, unedited and in order, because the chapter markers are the reason this description exists: they are what turns a 74-minute recording into something a volunteer can navigate to the family they are trying to name. The 62 titles run 2,761 characters on their own, more than half of YouTube’s roughly 5,000-character field, so the budget was found in the prose. The lede is two paragraphs, only three Q&A pairs carry over from the twelve in the archive package, and the resource list is three lines. The full narrative, all twelve Q&A pairs, and the complete resource block are in the website version.
Everything from the opening line through the footer above measures under 5,000 characters. Re-check the count after any edit, since the margin is thin.
Timestamp format follows Weeks 5 and 6, M:SS and MM:SS for the first hour and 1:02:49 style after it, rather than the H:MM:SS the project instructions specify for videos over an hour. Changing it for this week alone would put the last session out of step with what is already live on YouTube. This is one of the open course conventions the processing log flags for a decision across the whole course.
No family name is asserted for the click beetles. The 43:29 chapter titles the two field characters McHugh gives, the hinge and the tooth, which is what the Stage 2 chapter does. Block 579 in the corrected transcript is still an open flag.
