Chrysomela confluens
Chrysomela confluens is a leaf beetle in the family Chrysomelidae. Research demonstrates that this species exhibits dramatically elevated abundance in plant hybrid zones between cottonwood species (Populus), where staggered leaf phenologies create 'phenological sinks' that concentrate beetle populations. The species depends on newly flushed leaves for optimal growth and reproduction, and its distribution is strongly tied to host plant phenology rather than host plant taxonomy alone.
Tabanus fuscicostatus
Tabanus fuscicostatus is a species of horse fly in the family Tabanidae, first described by Hine in 1906. The species has been the subject of population-level research examining how parity rates—the proportion of females that have previously oviposited—respond to changes in host availability. Like other horse flies, adults are likely blood-feeders with females requiring blood meals for egg development, while larvae are typically predatory or scavenging in aquatic or semi-aquatic environments.
Trigoniulus
Asian millipede (informal, for T. corallinus)
Trigoniulus is a genus of millipedes in the family Trigoniulidae, established by Pocock in 1894. The genus contains at least 90 described species distributed primarily across tropical and subtropical regions of Asia. Species such as Trigoniulus corallinus and T. lumbricinus have been studied for their population ecology, revealing seasonal abundance patterns correlated with rainfall and temperature. The genus serves as a host for gut-associated microbes, including bacteria isolated from decaying plant habitats.
