Cuterebra abdominalis
rabbit bot fly
Cuterebra abdominalis is a species of New World skin bot fly in the family Oestridae. It is a parasite of lagomorphs (rabbits and hares), with larvae developing subcutaneously in host tissues. Adults are short-lived, lack functional mouthparts, and do not feed. The species exhibits Batesian mimicry, resembling bumble bees in appearance. It is one of approximately 34 recognized North American species in the genus Cuterebra, with seven species specializing on rabbit hosts.
Cuterebra austeni
Cuterebra austeni is a species of New World skin bot fly in the family Oestridae. The adult flies are large, bumble bee-sized insects with distinctive black and white coloration. Like other Cuterebra species, adults lack functional mouthparts and live only briefly, fueled entirely by larval fat reserves. The species has been documented exhibiting hilltopping behavior in Arizona, where males gather at elevated sites to locate females.
Hemileuca eglanterina shastaensis
Mount Shasta Sheep Moth
Hemileuca eglanterina shastaensis is a subspecies of sheep moth in the family Saturniidae, endemic to the Mount Shasta region of northern California. As a member of the Hemileuca genus, it is a day-flying moth with reduced mouthparts that does not feed as an adult. The subspecies exhibits the characteristic orange and black coloration typical of H. eglanterina, though with geographic variation associated with its isolated mountain habitat. Like other buck moths, its larvae possess urticating spines that can deliver painful stings.
Xenorhipis brendeli
Xenorhipis brendeli is a metallic wood-boring beetle (family Buprestidae) notable for extreme sexual dimorphism in antennae. Males possess highly modified, flabellate (comb-like) antennae with expanded distal segments covered in olfactory sensillae, while females retain the unmodified serrate antennae typical of the family. This species is the only member of its tribe occurring in eastern North America, ranging west to Minnesota and eastern Texas. Adults are short-lived, with males living no longer than 48 hours, and exhibit a narrow daily activity window focused on mate location via female-released pheromones.
