Insects

Insects are everywhere. In fact, insects and other arthropods comprise more than 80% of the world’s known animal species.

Plant lovers tend to like or dislike bugs based on what they do for (or to) our flora. We embrace bees because they pollinate flowers, and spiders because they eat more harmful bugs. Less welcome are destructive, plant-munching critters like winter moth caterpillars.

Love them or hate them, there are thousands of fascinating creatures to discover if you stop and look closely!
