The strange rainbow.
Lilianne nodded at what happened to the beetles, wary of the possibilities. "Better safe than sorry is the human expression, correct?" she said to the couple who only wanted to... pluck a few pears. "At this point we cannot say if this phenomenon could prove harmful and I insist you evacuate the area. Once we have a thorough examination and are sure there are no harmful side-effects, this place will be open to public access again. - Thank you for your understanding." the mage toold the two, then made a shooing motion.
She waited a few heartbeats for the couple to move away before addressing Esmeralda again. "I have the hunch the two were not coming hear to find some pears, the young man was more likely intent on plucking a different fruit, would you not agree Miss Najeet?" Lilianne remarked in a consirational tone and a smirk.
"But back to business." she told herself more than the gnome at her side. "Did you notice how the droplets stuck to the beetles and how there went a ripple through the rainbow effect? Now, look at the drops on their carapaces, they have some filaments still attached." the elf pointed out, letting Esmeralda catch up to her own observations before going on "So, this altogether reminds me of a spider's web. The way the droplets are sticky and interconnected. But I am not sure what kind of prey the creator of this web is hunting." she mused.
Allowing the other academician to share her opinion, Lilianne brought the vial and the stick back into her hands before scraping some of the droplets stuck to the beetle's backs also into the recepticle.
ooc: She is using the stick of course, not bare hands ;)
