Insects that you might see whilst on a walking or wildlife holiday in Spain
There exists a fascinating array of thousands of species of Bugs and beasties In Spain, with no-doubt some yet to be catalogued.
Of the more obvious and aesthetically pleasing, there is an impressive list of butterflies including the Apollo (Parnassius apollo) which is restricted to high mountains and the fabulous Spanish Moon Moth (Graellsia isabellae) on the endangered list due to greedy collectors. There are around 226 butterflies in Iberia and over 4000 species of moth.

Insects are often overlooked but we do rely heavily on bees which are an intrinsic part of our existence with their ability to pollinate crops. Cicadas whining in the trees during the heat of summer and crickets churring in the grasses at night are common insect sounds but have you ever searched the branches of a tree or bush for one?
Many insects are beneficial to us and yet are sadly targeted because of the “all insects are pests to be eliminated” attitude.
Moths which can be a nuisance fluttering around a lamp at night are important pollinators of white flowering plants. Lacewings which may become trapped in the house are needed outdoors as they are voracious eaters of the aphids that may reduce our crop yield.
While the use of chemicals such as pesticides can pollute our environment, nature usually has a better more balanced answer.
Among the many species of spider, southern Spain holds one protected by Europe, the Andalusian funnel web (Macrothele calpeiana) easily recognised by its all black colouring and long spinnerets. Iberia is also home to Tarantulas, though none resemble the huge tropical varieties.

- Mantis in Iberia are carnivorous insects that rest on plants while they await their prey. The size, colour and shape can vary greatly between species through their virtually world wide distribution, which consists of more than 1800 species. Within Iberia there are 15 species on the mainland with another on the Canary Islands.

Frequently Asked Questions: Bugs and Beasties in Spain
Spain is home to thousands of insect species and other invertebrates, many still being discovered. Expect to see a wide range of butterflies and moths, including the Apollo butterfly (Parnassius apollo) and the endangered Spanish Moon Moth (Graellsia isabellae). You’ll also hear cicadas buzzing in trees during summer and crickets churring at night. With over 1,700 species of spiders, Spain is a hotspot for arachnid diversity—look out for the Andalusian funnel web spider (Macrothele calpeiana), which is legally protected.
Most insects in Spain are beneficial. Bees are essential pollinators, lacewings control aphids, and moths pollinate night-blooming flowers. Harmful species are rare. Encouraging natural pest control reduces the need for harmful pesticides, making insects a vital part of Spain’s biodiversity.
Only a few species pose minor threats. Of the 1,700+ spiders, just three are considered potentially harmful. The Andalusian funnel web spider is more impressive than dangerous. Tarantulas in Iberia are small and not harmful to humans. The most notable risk comes from the Pine Processionary Caterpillar, which can irritate skin and be dangerous to pets.
In summer, cicadas produce a constant high-pitched buzz from treetops, while crickets serenade the night with their rhythmic churring. These natural sounds are iconic to warm Spanish evenings.
Yes. Specialist eco-tourism providers like Nature Plus – Grazalema offer insect-watching tours in Andalucia, focusing on spiders, butterflies, mantids, and dragonflies. Many tour companies listed on Wildside Holidays include invertebrate-focused excursions as part of their wildlife packages.
Several invertebrates are protected. The Spanish Moon Moth is endangered due to over-collecting, and the Andalusian funnel web spider is safeguarded under European legislation. Conservation efforts are growing as awareness of insect biodiversity increases.
Spain’s beetles (Coleoptera) and true bugs (Hemiptera) form the backbone of many ecosystems. They contribute to decomposition, pollination, and pest control. These small creatures play massive roles in maintaining ecological balance.
