Masoncus drama.

Remember Masoncus?

Well, I’ve been keeping them in the lab. I’ve found that they encounter similar issues with college dorm room residents, only they don’t have door-knobs for cliche gestures.

Notice Masoncus is “invisible” to their hosts.

The lab has made its Nat Geo debut

Check out the first blog entry over at National Geographic’s Explorers Journal.

There will be field updates that will accompany the upcoming Suriname trip.

The man in the rubber suit is back.

2014, I regress to adolescent excitement. I’m sorry, it’s only the king of all beasts.

Parts of the gland are sclerotized

Preparing glands for SEM imaging – making pelts of glands. Potassium hydroxide digestion leaves behind the sclerotized gland reservoir and ducts, while removing unwanted soft tissue.

Myrmedonota nr. defensive glands

Glands

Developing abdominal defensive gland in a 48 hour old Atheta coriaria pupa. Already a dense outline of type 1, D2 epidermal secretory cells are visible outlining the glandular reservoir, which itself is derived from the intersegmental membrane between tergites VI and VII. Pupal duration is approximately 96 hours long in this species.

The arrow indicates the cell-dense intersegmental invagination which is the defensive gland reservoir.

These images were taken with the help of entomology Steve. Thin sections were taken in epoxy embedded samples, then colored in a general stain – hence the blue. Thanks Steve!

Big fan of strong, attitude-pumped female vocal-centric groups, not to mentioned, I’m kinda into electro-pop right now. As I have, please totally rock out as you carefully contemplate the gland images as a representation of a key innovation – a key innovation that compartmentalized bodily glandular tissue into a collective organ, helps natural selection do it’s thing this way, at least that’s my working hypothesis. I said it first, just saying.
