Spotted tortoise beetle (Aspidimorpha miliaris)

Spotted tortoise beetle (Aspidimorpha miliaris) is a cosmopolitan insect in some families of Ipomoeaceae, Convolvuceae and Cucubitaceae plants. This species has perfect metamorphosis (holometabola) consisting of stages of eggs, larvae, pupae and imago.

The spotted tortoise beetle is about 15 millimeters long. Larva has gregarious habits. Imago uses wings to fly from leaf to leaf, but they prefer to walk quickly to navigate the surface and stalks to save energy.

A. miliaris performs a full cycle of 83-94 days in which the egg period to emergency pupa is 75-82 days and the pre-productive period is 8-12 days. Eggs are placed in groups in the ootheca and each group consists of 20 yellow-orange eggs. Females are able to produce 15 oothecas during life.

Eggs are oval, reddish yellow in ootheca grayish brown and last for 6-14 days. The pupa is yellowish, the back has black fur, lasting 10-14 days. Imago is shaped like a turtle with more yellow elitra.

Namib desert petal-bush (Petalidium namibense), previously confused with P. englerianum, P. rossmannianum and P. variabile

NEWS - Namib desert petal-bush ( Petalidium namibense Swanepoel & A.E.van Wyk, sp. nov.), previously confused with Petalidium englerianum , Petalidium rossmannianum and Petalidium variabile was established as a new species with a restricted range in the southwest, west and northwest of Puros in the Kaokoveld Centre of Endemism, northwestern Namibia. Currently, 41 species of Petalidium Nees von Esenbeck (1832) have been described in Africa. The main centre of diversity for the genus is in northwest Namibia and adjacent southwest Angola. Namibia is home to 31 species, while 13 species have been recorded in Angola, 6 in South Africa, and 33 species have been recorded in South Africa, Namibia, Botswana, Eswatini and Lesotho. During several expeditions to the Puros region, Wessel Swanepoel discovered an unknown Petalidium characterized by a dwarf shrubby habit, many stems from below or above the ground, white flaking bark (corky on older stems), long dendritic trichomes and flowers i

Matthias Asmuss pitcairnia (Pitcairnia asmussii) from Venezuela similar to Pitcairnia xanthocalyx Mart. 1848

NEWS - Matthias Asmuss pitcairnia ( Pitcairnia asmussii Gouda spec. nov.) discovered by Matthias Asmuss from Caracas, Venezuela, and cultivated at the Utrecht Botanical Gardens is similar to Pitcairnia xanthocalyx Martius (1848), but with shorter flower stalks with larger sepals and petals, and dimorphic, non-petiolate leaves. Pitcairnia L’Heritier (1788) is a mostly terrestrial genus widespread from Mexico to Argentina with a total of 217 species and about 52 species known from Venezuela. In 2015 Matthias Asmuss from Caracas collected a new Pitcairnia from Aragua, Venezuela. The specimen is kept in the VEN herbarium, but due to the chaotic period in the country, it may have been lost, only the photo remains. At Utrecht Botanic Gardens, Eric Gouda obtained a young specimen from the collection in November 2018 and it flowered in May (2024). This living specimen is next to the type specimen used for the description. Pitcairnia asmussii is an acaulescent or short caulescent plant, flow
