For honey bees, the male is the drone, the queen and workers are all female.
Drones' eyes are almost twice the size of a worker bee's eyes and their body is stockier and heavier than a worker, but not as big as a queen.
Despite their heavier weight, drones can fly fast enough to catch up with a queen.
Female spiders have food on their minds almost all the time. They having mating as an objective part of the time. When they have mating on their minds that does not stop them from wanting to eat. Male spiders have several ways of identifying themselves as being of the same species as the female, so that she will let them approach to mate with her. Then most of them have their own ways of keeping the female from eating them as or after they mate. Some male spiders sacrifice themselves. Some female spiders sacrifice themselves to their babies after the babies hatch.Eating the male spider after mating gives the male spider's genes a better chance of survival. So, evolutionarily speaking, it is an advantage to the male to have his progeny get a good start in life. The same is true of the female. Spiders species often live for only once season anyway, so it may be unlikely that either males or females of some species will get a second chance at reproducing.So female spiders eat male spiders because they are hungry, but also perhaps because evolution has not found it expedient in some cases to give the males a good way out. In other cases, however, the males almost always are not eaten. Some female spiders even tolerate males to continue living with them.
Different species vary - some spiders don't spin webs.. but it is not true that only female spiders spin webs - both male and female do - otherwise how would the male spiders catch their food?

The difference is that the females are normally bigger and stronger than the males.
Some species of female spiders do eat the male spiders after mating. Since spiders are intraguild predators, meaning that they eat each other, female spiders eat male spiders of the same and other species as food all the time.
Males have red stomachs

The males are smaller than the female
female caterpillars have little pincher's that come out the back of there body/butt that tell them apart from males males do not have this
the males have longer fins
DNA unless coloring different for that species between males/females.
the female parakets have lighter feathers and the males have dark feathers
males have smaller heads then females
females give birth.
Males are somewhat larger.
