Augochloropsis sumptuosa
sweat bee
Augochloropsis sumptuosa is a species of sweat bee in the family Halictidae, characterized by bright metallic green coloration. It belongs to the tribe Augochlorini, a group of small, often iridescent bees that are frequently mistaken for cuckoo wasps due to their similar appearance. The species has been documented in mark-recapture studies evaluating bee sampling methodologies, indicating its use as a representative taxon for monitoring wild bee populations. Like other Augochlorini, it is a solitary or primitively social bee that nests in soil or rotting wood.
Rhyssomatus lineaticollis
Milkweed Stem Weevil
Rhyssomatus lineaticollis, commonly known as the milkweed stem weevil, is a specialized herbivore associated with milkweed plants (Asclepias spp.). Adults feed on stems and leaf petioles, while larvae develop inside seed pods. The species is notable for its monophagous to oligophagous relationship with milkweeds, including the common milkweed (Asclepias syriaca) and the rare, threatened Asclepias meadii. Research indicates this weevil is relatively sedentary, with limited dispersal distances, functioning as a patchy population in fragmented agricultural landscapes. The species is distributed across eastern and central North America.
