JANUARY 2020 EDITION: ABN 2020 - 1 AFRICAN (NOVEMBER AND DECEMBER 2019) BUTTERFLY THE LEPIDOPTERISTS’ SOCIETY OF AFRICA NEWS LATEST NEWS Welcome to January’s newsletter! I hope you have all returned safely from your December holidays – assuming you had one – and had some memorable butterfly experiences. LepSoc Africa Annual Conference and AGM The 2019 LepSoc Africa Conference and AGM was held at Knysna Hollow, Knysna, over the weekend of 16 and 17 November. On Friday evening, before the conference, Hermann Staude hosted a Butterfly Evening, which was titled “Species, speciation and diversification, why are our butterflies and their hosts so exceptionally diverse?”. The evening included dinner at Knysna Hollow and was a great opportunity to renew acquaintances prior to the conference. Saturday involved a full series of talks and, in the evening, we held the society’s annual dinner and prize-giving at Belvidere. The winners of the major prizes were as follows: Torben Larsen Memorial Tankard (awarded to the best, or most influential publication on African lepidoptera), went to Hermann Hacker for “Moths of Africa – Volume 1” Ivan Bampton Perpetual Teapot (best life-history records) was awarded to Jean-Louis Amiet for “Natural Histories of the Butterflies of Cameroon” Steve Collins accepting the Honorary Life Membership of LepSoc Africa was awarded, Ivan Bampton trophy on behalf of Jean-Louis Amiet posthumously, to Dr Martin Krüger for his immense contribution to our understanding of African lepidoptera. The certificate was accepted by Martin’s widow, Kerstin. 1 The Chairman’s Award was given to Hanna Edge in recognition of her considerable efforts in refining the LepSoc Africa membership list, following up with subscription payments and assisting members with any queries they may have had. Our Annual General Meeting was held on Sunday morning; as all relevant information had been circulated to the LepSoc Africa membership beforehand, we were able to run through all issues relatively quickly and, for the first time that I can remember, concluded the AGM on time. Bennie Coetzer ran through some of the issues and challenges that need to be addressed regarding the future of Lepibase. A panel is being set up to drive this process, which is central to the society’s research and conservation objectives. There were a series of talks following the AGM, which was followed by an “old-style” photographic competition, hosted by Andre Coetzer. The entries were judged by a show of hands by those present. The winning entries are showcased below: Fun Scientific Pictorial Go away… Hewitsonia boisduvalii emitting Papilio Zalmoxis in flight (submitted by Hermann Staude) pheromones (Jeremy Dobson) (Jeremy Dobson) To conclude, I believe Knysna 2019 was one of the most enjoyable (and well attended) conferences in the recent history of LepSoc Africa. Special thanks to those who travelled considerable distances to be present, such a Steve Collins, Josiane Goossens and Szabolcs Sáfián. Finally, thanks to Dave and Hanna Edge for making it all possible. The 2020 conference will be held in Johannesburg or Pretoria over the weekend of 13 and 14 September. 2 A list of the presentations and presenters is included below: • The impact of climate change on African Lepidoptera (Jonathan Ball) • The SALCA Project – summing up and recommendation (Silvia Kirkman) • Monitoring the impacts of climate change on Lepidoptera (Kerstin Krüger) • The Perspective from ABRI (Steve Collins) • A butterfly abundance index for South Africa (Jeremy Dobson) • Knysna Sand Fynbos – a case study of landscape conservation (Dave Edge) • The Kedestes butterfly conservation project (Louise Baldwin) • Can the Brenton Blue be saved?

Raimund Schutte and Mark Williams were going to join me, but Mark reflected that the recent Zambia and Malawi trip had taken too much out of him and that he needed more time to recover: Mark didn’t take this decision lightly - this is the first LSA conference that he’s missed since the Society’s inception in 1983. Raimund and I set out from Johannesburg early on Monday 10 Nov. Our first stop was a site near Wepener, eastern Free State, that Chris Dobson and I had “discovered” many years ago. It’s usually a great spot for Koppie Giant Cupid (Lepidochrysops ortygia) and Karoo Russet (Aloeides gowani) and I had even found a couple of Karoo Giant Cupid (Lepidochrysops southeyae) there a few years ago. On this occasion, we saw very little, apart from a few Patrician Giant Cupid (Lepidochrysops patricia) and Desert African Three-ring (Ypthima asterope hereroica). The only record of note was a solitary Henning’s Marbled Sapphire (Stugeta bowkeri henningi). We headed on for Sterkspruit, where I’d found L. southeyae and Maluti Russet (Aloeides maluti) in 2010, but we didn’t find much this time. The weather was clouding over, but we drove Joubert’s Pass just for the hell of it and stayed at a nice B&B in Barkley East (the town is Leptomyrina lara Wepener, Free State desperately short of water and the water supply was cut on the day of our departure). On our second day, we visited the Tsomo area, where I have seen some great butterflies over the years, including Southern Purple (Aslauga australis) and Tsomo River Opal (Chrysoritis lyncurium). No Aslauga on this occasion (we saw a solitary lyncurium), but we did find several Mbulu Russet (Aloeides mbuluensis), which was new for me. We searched an adjacent hill, where I’d located a colony of Aloeides dentatis-like butterflies a few years ago, but we were possibly too early in the season. On a sad note, there used to be a large Yellowood Chrysoritis natalensis forest nearby, containing several forest butterflies, including Tsomo, Eastern Cape Yellow Hindwing Dotted Border (Mylothris trimenia) - Tsomo Mountain Blue (Harpendyreus tsomo) being found in the surrounding grassland. In the space of 5-years the forest and grassland has completely disappeared and has been replaced by wattles and goats. We reached Hogsback that evening and visited Gaikas Kop the following day. Ground Hornbill Tsomo, Eastern Cape 4 Gaikas Kop was great - loads of browns, such as Vári’s Brown (Pseudonympha varii) and Dark Speckled Widow (Serradinga bowkeri bowkeri), and a couple of Russets: Aloeides dicksoni and Aloeides almeida - I think the latter record is a significant range extension. A highlight was seeing a couple of Pennington’s Opal (Chrysoritis penningtoni); I think Raimund and I are some of the first people to photograph this species in the wild. Other butterflies included Barber’s Ranger (Kedestes barberae barberae), Nosy Cupid (Orachrysops nasutus nasutus) and, on the summit of the mountain, a couple of Variable Giant Cupid (Lepidochrysops variabilis). The Bamboo Sylph (Metisella syrinx) and East Cape Giant Cupid (Lepidochrysops grahami) were not flying - we were probably a few weeks too early. Chrysoritis penningtoni Orachrysops nasutus nasutus Stugeta bowkeri bowkeri Gaika’s Kop, Eastern Cape Gaika’s Kop, Eastern Cape Jansenville, Eastern Cape Next up was Jansenville, where we saw a few Beulah’s Opal (Chrysoritis beulah) and Bowker’s Marbled Sapphire (Stugeta bowkeri bowkeri), before overnighting in Uniondale in preparation for the following day‘s Kammanassie adventure. LepSoc Africa had advertised the Kammanassie trip as an optional extra activity for conference delegates and Raimund and I were joined by Andrew Morton, Johan Greyling and Andrew Mayer. Originally, we’d planned to camp on the mountain on Thursday night but, based on the weather forecast, Chrysoritis beulah we decided to cancel the camping and make it a day trip on the Jansenville, Eastern Cape Friday. The Kammanassie looked beautiful - it’s always a privilege to visit this mountain range - but butterflies were scarce. Nonetheless, between us, we recorded most of the special butterflies found on the mountain, such as Kammanassie Giant Cupid (Lepidochrysops balli), Kammanassie Giant Russet (Aloeides pallida jonathani) and Ball’s Opal (Chrysoritis pyramus balli); no sign of Kammanassie Cupid (Orachrysops brinkmani) unfortunately. Our thanks to CapeNature for permission to visit the mountain and to Dave Edge for arranging access to Kammanassie with the local farmers. Lepidochrysops balli Lepidochrysops robertsoni Aloeides pallida jonathani Kammanassie, Western Cape Kammanassie, Western Cape Kammanassie, Western Cape 5 We arrived in Knysna on Friday evening, in time for the Butterfly Evening and the weekend’s LepSoc Africa conference (refer to the preceding article). On Monday, following the conference, Dave had arranged for various groups to search for the Brenton Cupid (Orachrysops niobe). A prize of R20 000 has been put up for the first person to rediscover this butterfly, which disappeared following the Knysna fire of September 2017.
