OWN said he'll be off for a couple of days so suggested me or Imberbe. So I'll ask an easy one that Imberbe can answer - or anybody else as well of course.

This (species of) insect has a unique relationship with rhino. What is the insect, and what is the relationship?

bishop3006,
when you say "unique", does this mean this insect does NOT have the same relationship with other animals, but ONLY with rhinos? thanks!

Is it one of the 4 species of ticks that only feed on rhinos and the attendant oxpeckers that feed on them and alert the rhino to predators and poachers?

Care to answer Imberbe, so we can carry on, or would you rather wait for bishop3006?

No Elzet, not the rhino beetle either. :? And Imberbe is doing the same as OWN and disappearing on us? :naughty: :naughty:

This actually comes from IMBERBE #12: VIRTUAL BUSHWALK (QM) thread: (I'm reading all the quizzes again and making notes not to forget...)

There are three genus that I know of that are associated with rhinos and their middens.

The first is Gyrostigma rhinocerontis - rhino bot fly. It lays its eggs on the rhino's hide - often near the horn. The maggot enters the rhino via the mouth and nose and attaches itself in the gut. It goes through three instars, exits via the anus, pupates under the dung and then becomes a short lived adult.

The next is a species of Lyperosia and the last a biting fly Rhinomusca dutoiti.

Particularly the first and last's numbers drop alarmingly where rhino numbers are low and would probably go extinct without them.


Africat and Elzet, since you both tried, first one to post can be it. :thumbs_up:

Hi friends,
I did read an interesting article about the fact that people are so passionate about saving the "big" animals, such as rhino, but don't realize how many other small species will also become extinct if they do, such as the 4 species of ticks and the bot flies, etc.

I (erroneously) interpreted the word "relationship" to mean both benefited in some manner. The ticks do bring the oxpeckers who act as sentinels, but I couldn't find any benefit of having a fly buzzing around and laying eggs in your...uh, well...nethermost parts, so I chose ticks. Wrong! Bring in the hook!

Elzet, since my answer was not even an INSECT, you win the booby prize...go for it!

In the Kalahari region, there is an insect whose defense strategy has triggered an evolutionary response in an entirely different kind of animal species. The model emits a noxious acid which predators avoid, while the mimic mirrors both the coloration and gait in order to receive the anti-predator protection via deception (Batesian mimicry).

What is the model, and what is the mimic?

I'm not always right, but knew that you were a 'she-devil' :mrgreen:

Natural selection for juvenile lizards mimicking noxious beetles
RB Huey and ER Pianka

Adult Eremias lugubris in southern Africa are concealingly colored and move with a typical lizard gait, but the jet-black and white juveniles are conspicuous and forage actively with arched backs. In color, gait, and size, juveniles mimic "oogpister" beetles (Carabidae: Anthia) that spray an acidic, pungent fluid when molested. This unique mimicry, which is believed to be the first reported case of a terrestrial vertebrate mimicking an invertebrate, seems to reduce predation on juvenile lizards.

Ok, so here goes...

Many, many moons ago farmers from a specific country prayed for good crops. Then the insect in question appeared in huge numbers and assisted the farmers by devouring crop-devastation bugs and consequently rescued farmers' crops. In honor of these crop-saving bugs, the farmers named these insects ........, which is a .............. as we know it today.
