The Creepy-Crawly Guide to Insects in Spanish: Free Printables and More!

Some bite, sting, and stalk their victims, while others zip, zoom, and fly around our heads on a hot day—the fact is, insects are everywhere. There comes a time in every Spanish learner’s life when you must learn about the little creatures who creep about in the night (or day). Let’s learn about insects in Spanish!

The common way to refer to insects in Spanish is to say los insectos, while los bichos is also perfectly acceptable. Then there are synonyms like las alimañas (pests), las plagas (plagues), and las sabandijas (creepy-crawlies) that signal the damage and discomfort these creatures can cause.

For those of you who like to get really specific about bugs, we’re dealing entirely with arthropods in this post, which includes los insectos y los arácnidos (arachnids). 

Arachnids and Insects in Spanish: What’s the Difference?

To break down the differences between arachnids and insects in the simplest way, we’ll stick to one major distinction:

• Arachnids have 8 legs
• Insects have 6 legs

If you’re into etymology, the vast differences between these two classes in the phylum are long, detailed, and truly fascinating (but completely outside the scope of this article!). To further explore your curiosity, read more about it here.

At some point, you’ve likely mentioned how los mosquitos te molestan or how you saw una abeja en el jardín. Those are basic insects that are essential to know. Now let’s build up your vocabulary skills by adding even more insects in Spanish!
