Bombus sylvicola
Forest Bumble Bee, Forest Bumblebee
Bombus sylvicola, the forest bumble bee, is a North American bumble bee species with a broad distribution across Canada and Alaska, extending into the western contiguous United States. In California, it occurs only at high elevations, making it a high-altitude specialist. The species has been identified as particularly vulnerable to climate change, with rising summer temperatures threatening its populations. Research indicates that B. sylvicola is among the cool-adapted bumble bee species experiencing decline due to warming temperatures.
Calliphora livida
slow-flying and loud-buzzing blue bottle fly
Calliphora livida is a blow fly in the family Calliphoridae, commonly known as blue bottle flies. It is a medium-sized fly with a blue metallic sheen dulled by dense micromentum. The species is widespread across North America and is notable for its relatively delayed arrival on carrion compared to other blow flies, typically appearing approximately 24 hours after death. It prefers cooler, shaded environments with temperatures ranging from 4 to 15.6°C. The species holds significant forensic importance for post-mortem interval estimation, particularly during spring and colder months when other blow fly species may be less active.
Rhopalosiphoninus latysiphon
bulb-and-potato aphid
Rhopalosiphoninus latysiphon is an aphid species that infests subterranean plant parts, particularly potato roots and bulbs of ornamental plants such as tulip and gladiolus. Its common name reflects its association with both bulb crops and potatoes. The species is distinguished by its preference for cool, damp environments and avoidance of above-ground foliage under normal field conditions. Two subspecies have been described but may be synonyms.
