Thought I'd shed some light on the anthropological reasons Europeans and descended communities in the US and Canada and other former settler colonies don't really eat insects (that I'm taking on total faith from some anthropologist).

There is not as many insect eating traditions in Europe due to the climate in comparison to the tropics. This carried over in Indigenous North American communities too. 25 to 50 percent of native communities had insect eating traditions, but they clustered where there was large insect biomass like the west coast or plains (not that there wasn't insect eating in communities with other food sources, there were just less). It also did exist in Europe to a lesser extent. Fried silkworms were eaten in Italy, Ukraine had an ant based liquor to make medicinal punches, Sardinia has a cheese with larvae in it. However due to the cold and construction of sealed buildings (a dwelling in the tropics has to be much more open to the environment than in northern Europe) and stronger reliance on insect sensitive crops, a stronger tendency to view insects as pests instead of food emerged. Eating insects was something done in a lot of communities as a famine measure primarily. Romans and Greeks ate insects, but not as a staple food.

Some settler communities in the America's did develop (if short lived) insect eating traditions. One reason these were not propagated was possibly due to indigenous insect eating being used as a "primitive" trait against indigenous peoples and it was discouraged by missionaries and in the schools children were forced into. It also became a class issue, where insect eating was a poor person's food (if you were a poor farmer and your harvest got fucked, you're eating grasshoppers). Some white communities did have insect eating traditions occur though, mostly in the great plains.

To sum up I think it's a combination of low insect biomass in cooler climates combined with crops (if you have to actually farm insects, less likely to do so), which then became entrenched with colonial and classist attitudes. There's also maybe some religious aspects like Deuteronomy forbids eating winged insects (dunno why), but some insects like locusts get an exception. One thing to note on biomass and availability is that one of the few insect dishes in France and Germany till the 1950s, Mai Bug soup, was only made because of large beetle swarms in spring.

I've heard the trend of insect eating being acceptable in areas where it can be more than a marginal food is also seen interestingly in Jewish communities. Ashkenazi Jews are less likely than Sephardic Jews to view certain insects as kosher (guess which one coalesced as a community in the colder climate). No clue if this is actually true though.
