Large longicorn repeatedly appearing at this time of year

 

PHOTOS & OBSERVATIONS: Dewald Kamffer, Modjadjiskloof.
Published to iNaturalist at his request and with his permission.

 
Adult longhorn beetles of this species found in citrus trees in home garden. Found in different citrus species & varieties: oranges and lemons and grapefruit and naartjie|tangerine. The beetles cause great damage by feeding on leaves. Larvae or their activity not seen yet; perhaps they do not develop in citrus stems|branches; observations are continuing.

It seems that the adults of this 'bycid emerge after the first good rain, which nowadays at this location falls in November. The adult beetles are common in a pesticide-free home garden, but—despite frequent visits there—are not seen in commercial citrus orchards. Commercial orchards in this region are heavily dosed with chemicals at this time of year.

Body length of adult c. 13–15 mm.

Polyspilota sp. from paradise

 

PHOTOS & EXPERIENCE: Gimo M Daniel, Bloemfontein.

 
I think the mantis in Gimo's photos above is a female.
EDIT:
The mantis in Gimo's photos above is a male.

 
Gimo's mantis is a rather good match for the unidentified Polyspilota sp.2 reported from Rwanda by world mantis expert Gavin Svenson and his colleagues in the 2015 paper cited below. The Svenson expedition to Rwanda yielded three Polyspilota species, not one of which was identifiable to species level.

Polyspilota is an Afrotropical genus, currently with about ten valid species. Three of those species are restricted to the islands southeast of the continent. Polyspilota aeruginosa is common and widespread from South Africa to West Africa, plus Madagascar. Polyspilota caffra and Polyspilota magna are confined to southern Africa. The remaining five Polyspilota species occur in different parts of tropical Africa, but their distributions are very poorly known. There should be no doubt that there are additional, unnamed species yet to be collected and described. Gimo's mantis from Mt Mabu may easily be an undescribed species.

In the paper cited below there are two clear photographs of the Rwandese Polyspilota sp.2:

  • Fig. 5H (♀ in life).
  • Fig. 19D (♀ mounted).

Die Geel Gevaar


10 years ago this was a happy suburban vlei with birds, fishes and butterflies. It has subsequently become completely clogged with a large variety of alien invaders. This yellow one seems to be new. >100 plants, up to 220 cm tall. Seems confined to c. 100 square meters. Growing strongly, flowering profusely at present. I must have overlooked them in recent years.
 
I am worried. Identification and advice, please. I can make a herbarium sample if necessary.

Description

Silky Oak -- Being invaded by indigenous vegetation?


? See this project: http://www.ispotnature.org/projects/silky-oak

For about 230 m along this road a row of Silky Oaks stands on either side. The trees are old; some seem to be decrepit or dying. Have a look at the satellite view, and especially Google Streetview, to appreciate what may be going on here. It's almost as good as going there. Don't go as far as the casuarinas or the pines on the northern side of the road. The current Streetview imagery is, unfortunately, from mid-winter.

On the northern side of the road (left on the pictures), it seems like the Silky Oaks were planted as a windbreak for the orchard just behind them. I think those are almonds. I have no such a neat explanation for the opposite row of trees. Enough money for symmetry, perhaps. Must have been beautiful when young.

I assume that the windbreak and opposite row were cleared of indigenous vegetation when they were newly planted, how many decades ago. Now, the rows of ageing Silky Oaks are unkempt, and a fair number of different indigenous trees and shrubs (and trees-as-shrubs) have infiltrated the Silky Oaks. In some stretches the indigenous vegetation seems to dominate the planted trees, which are taller. In places it looks like the bush that must have been present there before the area was cleared for agriculture.

Compared to undisturbed areas in close vicinity, the natural bush on this farm and the others along this road was completely destroyed, I assume when the area was settled and tamed. Colonised, one could say. That could have been towards the end of the nineteenth century, but that then at the earliest. The species of tree and shrub that are infiltrating the Silky Oak avenue are typical of topographically comparable undisturbed remnants of veld in De Tweedespruit. The "invaders" here include Silver Clusterleaf Terminalia sericea, Buffalothorn Ziziphus mucronata, some acacia shrubs or trees, and even Savanna Protea Protea caffra. Except for the Vachellia on this little list, I have no knowledge that any of the other species are ever significant bush encroachers, and probably also not usually pioneer species. I assume that the Silky Oaks created suitable microhabitat for them to establish and persist, and -- importantly -- that the farmer gave up clearing.

Most unsurprisingly the incursion is not only of indigenous plants. I can recall Bugweed Solanum mauritianum and Cherrypie Lantana camara also being there, and perhaps also Yellow Bells Tecoma stans, but of the last one I'm not sure.

Have another look at the satellite view: these fringes of bush are really narrow, probably kept from expanding away from the road because of ongoing agricultural clearing or simply routine agricultural activity. That makes me wonder if the indigenous plants invaded the planted rows in a linear manner -- did not think of this on the day I took these ugly pictures.

These pictures were taken in a hurry while I was doing something very different (and truly out of the ordinary). I hope to return to this avenue in future to explore and document the situation with more attention.

Number of individuals: c. 200 (planted in rows, ageing).
Size class: 4–8 m, or >8 m.

Silky Oak -- Not obviously invading anything


? See this project: http://www.ispotnature.org/projects/silky-oak

Pictures of a tree taken long before Rabelani's project was initiated, hence no tailormade observations. Along this dirt road in a farming area there are the occasional large Silky Oak, which I assume have been planted there.

Start at this location, where this tree is clearly visible on Google Streetview. Then drive up and down the De Tweede Spruit road with Google Streetview to get a rather good impression of the Silky Oaks at the side of the road. I cannot discern any baby trees, but I'm not too sure what they look like. Unfortunately the current Streetview version is in the middle of winter.

Number of individuals: Occasional along road.
Size class: 4–8 m, or >8 m.

Sea pumpkin


On beach, low spring tide: hundreds of these "pumpkins" lying in shallow water. It is apparently important to note that the beach sand was deeply washed away. It was night.

Pumpkins as in pictures. Enormous, fleshy things. The one collected and shown here was one of the smallest; size up to double this. Flesh really juicy, no smell, no taste -- seems to be all fresh water. Is this a plant's underground storage organ?

Twig with leaves came along later, donated by a stranger. If the leaves do not belong to the pumpkin, I shall remove them.

First opinion was that the pumpkins were washed ashore from the coral reefs. That lead to the identification of the pumpkins as algae.

Second opinion was that the twig & leaves, dug up from the beach sand, belong with the pumpkins. A stranger gave me the gift of a small sample of his larger sample.

Third opinion, by another stranger, was that these pumpkins belong to the Asteraceae. I have no idea why.

What are sea pumpkins?

Chafer asana


It was raining and the chafers were too cold to fly. They clung to vegetation, either with the head up, or with the head down. All four individuals I saw were frozen in the same yoga position: holding on with the two front pairs of legs, but the hindlegs are spread up and out as far as they can go. They retained this position when lightly pestered by me.

I don't know what they were doing. I don't know if this is some form of crypsis, or even a form of mimicry. In the upside down position, the two areas of whitish scales may look like eyes. Are they also reverse-painted? The outstretched hindlegs may look a little spidery.

Any thoughts on this pose?

Invader in paradise -- Yellow Bells


Multistemmed bush some 3m high. Leaves imparipinnate, leaf margins clearly serrate. Clusters (Racemes) of yellow trumpet flowers with faint stripes in their throats. No fruits visible.

Invader from Mesoamerica. Introduced as ornamental plant. Now occurring frequently in 5 provinces of South Africa, rarely in two more; also neighbouring countries. Potential 'transformer' weed with the ability to form dense monocultures, thereby altering ecosystem structure, integrity and functioning.

One of a group of 'emerging weeds' identified as such in 2004. Biological control currently being researched. One biocontrol agent already released, more to follow.

I have known these lichens since childhood, but never learnt anything about them yet. It seems that they are specific to the bark (trunks and main branches) of White Stinkwood Celtis africana, but that is probably untrue for the reason that I have not been able to recognise them on other substrates.

The lichens range in size from imperceptibly tiny to around 20 or 25 cm across. Old colonies die off from the centre, as seen in the second & third pictures.
