How to Procrastinate: Studies in

no, royalties are not a significant source of income for most authors. if you wrote something like Project Hail Mary, then absolutely, the royalties would be substantial! but that's like winning the lottery. Ryan Gosling is not starring in the movie adaption of most books.

when you sell a book to a publisher, you get what's called 'an advance against royalties'. it's usually split into multiple parts, so you might get one third for the initial sale, one third for the final revised manuscript, and one third on the publishing date.

an advance against royalties is the publisher saying "we believe you will eventually make X amount in royalties, so here it is ahead of time." and then you don't actually see any money from royalties until the advance is paid off. most books do not make enough in royalties to pay off the advance (I have two children's books and one fiction book, and have yet to see royalties for any of them).

advances are still great, but you need to make them stretch! for instance, last year my net income was about 30k Canadian (21k USD), which is fantastic when you consider that I mostly made it through writing. but I'm definitely not a millionaire. I can live off my writing (not trying to undersell that!) but I'll probably remain in a low income bracket for the foreseeable future.

Harvestmen, otherwise known as daddy long-legs (not to be confused with the cellar spiders of family Pholcidae, which are also described as daddy long-legs) bear a striking resemblance to spiders, but they actually belong to a separate order of arachnids known as Opiliones. These strange-looking creatures have eight legs, but only two eyes, and their body segments are largely fused together, giving the body a noticeably rounded, pill-like appearance.

There are roughly 6,700 known species of harvestman, but researchers estimate that a total of more than 10,000 species may currently exist. Their physical features vary greatly from one species to the next; some harvestmen have crab-like claws, spikes, thorny legs, elongated bodies, colorful features, or cryptic markings. Most of them are equipped with long, spindly legs, but there are some that have shorter, stockier limbs instead.

Unlike spiders, harvestmen have an omnivorous diet that includes fungi, fruit pulp, seeds, pollen, lichen, algae, and invertebrate prey, and they are capable of consuming solid food, whereas spiders are typically carnivorous and feed only on fluids.

As this article explains:

Harvestmen consume mushrooms, fruit pulp, seeds, and seed appendages more frequently than spiders probably because they are “solid food feeders," which means they can ingest solid tissues by biting off small pieces. In turn, spiders are “fluid feeders” and feed on vegetable matter most frequently in the form of fluids (e.g. nectar, stigmatic exudate, plant sap, and honey dew) rather than fungal or plant tissues.

When given a choice between fresh fruit or invertebrate prey, some harvestmen actually prefer the fruit:

Schaus et al. carried out a feeding trial in which the Neotropical harvestman Erginulus clavotibialis was given a choice between fresh pineapple and live invertebrate prey. This harvestman demonstrated a distinct preference for fruit over the invertebrate prey.

Harvestmen are also much more social than spiders, and the males of some species have been known to engage in paternal care, which is a trait that rarely occurs among arthropods:

Single fatherhood is the rarest form of parental care in nature. Still, males are often the sole caretakers of progeny among a number of species of daddy long-legs, also known as harvestmen. In these species, fathers are exclusively responsible for guarding eggs that females lay on the undersides of leaves; the males remain on the eggs nearly constantly for months.

When threatened, harvestmen often bob up and down erratically in an effort to confuse their attackers. They also have several other defense mechanisms, including pungent, foul-tasting secretions, the ability to "play dead," and autotomy, which is the ability to discard one or more of their own limbs in order to escape from predators.

Harvestmen are completely harmless to humans. Their mouthparts are far too small to penetrate human skin, and contrary to popular belief, they do not have the "world's deadliest venom" -- in fact, they don't produce any venom at all.
