chrysanthemum aphid

The chrysanthemum aphid (Macrosiphoniella sanborni) is a soft-bodied insect in the family Aphididae, a specialist pest of cultivated and wild Chrysanthemum species and related members of the family Asteraceae. It is a dark brown to reddish-black aphid, distinguishing it from many green or pale aphids, and infests the shoots, leaves, and flower buds of its host plants. Like other aphids, Macrosiphoniella sanborni feeds by inserting its stylet mouthparts into plant tissue to extract phloem sap, depriving the host of carbohydrates and amino acids. Heavy infestations cause stunting, leaf curl, distortion, and reduction in flower quality and yield, making it a significant pest in the commercial chrysanthemum industry worldwide. The species can reproduce parthenogenetically — females producing live young without fertilization — and populations can build rapidly under warm greenhouse conditions. Chrysanthemum aphids excrete honeydew, which supports the growth of black sooty mold on plant surfaces, further reducing photosynthesis and ornamental value. They may also transmit plant viruses during feeding. Natural predators including ladybirds, lacewings, and parasitoid wasps provide biological control, though chemical aphicides are frequently used in commercial cultivation.

Common Elephant Tusk

<em>Antalis entalis</em>, the common elephant tusk, is a marine mollusc in the class Scaphopoda, family Dentaliidae, classified as Least Concern by the IUCN Red List. The species is native to European waters and has been documented in Denmark, Norway, and Sweden, inhabiting subtidal and deep benthic zones of the northeastern Atlantic Ocean and North Sea. As a scaphopod, <em>Antalis entalis</em> is characterized by its distinctive curved, tusk-shaped shell that is open at both ends, allowing the animal to partially burrow vertically into sandy or muddy substrates with only the narrow posterior end projecting into the water column. The species feeds on foraminifera and other microscopic organisms in the sediment, capturing prey with specialized tentacle-like structures called captacula that extend through the broader anterior opening of the shell. Scaphopods have limited locomotion and typically remain partially buried throughout their lives. <em>Antalis entalis</em> plays a role in benthic communities as both a consumer of meiofauna and a prey item for predatory fish and invertebrates. Historically, elephant tusk shells of related species were used as currency and ornament by Indigenous peoples of the Pacific Northwest coast. Biological traits of this species remain poorly documented in the scientific literature.
