Gynandromorphism
Guides
Hylaeus modestus
modest masked bee, yellow-faced bee
A small, nearly hairless solitary bee in the family Colletidae, native to North America. Females transport pollen and nectar internally in a crop, then regurgitate it into brood cells lined with a secreted polymer. The species has been observed visiting annual flowers in garden settings and is a generalist forager. A gynandromorph specimen with bilaterally asymmetric male and female characteristics was documented from Ontario, Canada.
Myrmarachne formicaria
Ant-mimicking jumping spider
Myrmarachne formicaria is an ant-mimicking jumping spider (Salticidae) native to the Palearctic region and introduced to North America. It is one of few Myrmarachne species found outside the tropics. The species exhibits sophisticated locomotor mimicry, walking with all eight legs while adopting ant-like postures and movement patterns. It was first recorded in the United States in Ohio in 2001 and has since spread to multiple states.
