Adriana Hoffmann Jacoby
Born 1940. Standard IPNI form: A.E.Hoffm.

As a Chilean botanist and environmentalist, Adriana Hoffmann Jacoby has authored over a dozen books on the flora of Chile and has identified and classified more than 100 new species of cacti. She was Chile's Environment Minister in 2000 and 2001. She has advocated for the sustainable management and protection of Chilean forests, leading opposition to illegal logging in her role as coordinator of Defensores del Bosque Chileno (Defenders of the Chilean Forest) since 1992.

Hoffmann was recognized by the United Nations in 1997 as one of the 25 leading environmentalists of the decade for her efforts to protect Chile's forests. In 1999 she won the National Environmental Prize in the category of Environmental Education, awarded by Comisión Nacional del Medio Ambiente (CONAMA). For her research into Chilean flora and her work in environmental education, Hoffmann received the Luis Oyarzún Award from the Austral University of Chile in 2003. She received a Fellow Award from the Cactus and Succulent Society of America in 2009.

Hoffmann has also served on the judging panel for the United Nations Environment Programme's Sasakawa Prize.

Five-horned Beetle

Eupatorus gracilicornis

Eupatorus gracilicornis

Some facts on this beetle:

Length: 50-95 mm.

Larva Diet: Rotten wood.

Adult Diet: Nectar, plant sap and fruit.

Range: Southeast Asia.

First described: By the British entomologist Gilbert John Arrow in 1908.


A rhinoceros with five horns? Well, Eupatorus gracilicornis is not quite a rhinoceros but nevertheless it is a fascinating creature. This extravagant beetle is boldly colored with shiny jet-black while the elytra or fore wings are colored yellow or gold. It has four large horns on the pronotum (the foremost thorax segment) and one extra-long cephalic (of the head) horn. The body is covered by a thick exoskeleton and a pair of thick wings lie atop another set of membranous wings underneath, allowing the beetle to fly, although not very efficiently, owing to its large size. The flying season is usually in September, when most of the males usually appear to wait for copulation. Rhinoceros beetles - the Dynastinae, are a subfamily of the scarab beetle family - Scarabaeidae. They are also known as Hercules beetles, unicorn beetles, or horn beetles. There are over 300 described species of these beetles, best known for their bizarre shapes and large size.
