Waaouu! Haughtiness

Waaouu!

Haughtiness photographs!
Thank you for distribution!

I made a try of animal husbandry. I unfortunately did not succeed in making a full cycle. The females had not laid.

This variant is very nice.

Common Name

How about "Friesian Chafer"?

A very variable fruit chafer species

.
|ONE|

In southern Africa we have quite a couple of black fruit chafers with white spots, and several of them are variable with regard to the exact number, shape and placement of the white spots (called 'cretaceous markings'). Mausoleopsis amabilis is a common black-&-white fruit chafer that is rather stable in the location and extent of its cretaceous markings, as can be seen in other iSpot observations. Compare the chafer in this observation with M. amabilis and you will speedily notice that the exact pattern of white markings differs here. For starters, the two large white patches at the lateral margins of the elytra are connected in this observation, whereas they are always quite separate in M. amabilis. The very quality of the white markings are also different: almost shiny and like enamel in M. amabilis, but rather milky here. Another important difference is that in this observation the beetle is dull, matte (except on its elytral ridges), whereas M. amabilis's integument is shiny and like lacquer, and without ridges in this particular configuration. There are numerous structural differences as well.

I just made up the common name "Variable Fruit Chafer" for Elaphinis delagoensis [this observation]. But, concerning its colour pattern, it is one of the most variable fruit chafers in our region. Would you believe that ispot.org.za/node/168681 (black with other white spots, and some brown), as well as ispot.org.za/node/168667 (completely different!) are specimens of the same species? They surely tricked the photographer, who photographed all three at the same place and on the same day, but contributed them as three separate observations! [I think it should be left like this]. The simultaneous occurrence of these three very different liveries argues against them being subspecies. Indeed, even more colour patterns are known in the species, and they do not occur in any geographically structured pattern.

Good Work!

Thanks.

I presume that these dudes are not using colour or pattern - at least in our part of the spectrum - for mate recognition.

Which begs the question: do any of the other Scarabs, or is it mainly pheromonal?

UPDATE: >>> three separate observations

Make that four separate observations. This one was added tonight. vynbos reckons this species should be called the 'Helluva Variable Fruit Chafer'.
