I have studied biology at the University and I am a specialist in Ancient Natural History of  insects, collaborator of Zoology Museum of Barcelona and member of the Catalan Institute of Natural History (ICHN). I have spent about forty years studying entomology and I have traveled in several countries around the world. There, I have been witness to the enormous biodiversity that still exists on the planet.

I am the author of two works related to insects, both written in Spanish language and freely available on this site: Bands, swarms and devastation. Locust plagues throughout history (Almuzara, 2007) and Insects and hecatombs , volumes I and II (RBA, 2012 and 2014). In June 2018 appeared History of flies and mosquitoes (published by Arpa), and in September 2019 was published my last work, Passion for insects. Ilustradoras, Viajeras, Coleccionistas and Entomólogas (published by Turner), a small history of entomology from the exceptional work of fifty-one women who had dedicated themselves to the study of insects. At the end of this page you will find links to articles and interviews about this work.

In the first work there are described the most dangerous locusts species and the most important pests that man has suffered since Neolithic, just when it started. Second work is a natural history about insects like fleas, lice, mosquitoes, flies, chiggers and also ticks; and descriptions around most of diseases transmitted by them: plague, epidemic typhus, yellow fever, malaria, filariasis, African trypanosomiasis, Chagas disease, etc. All this stuff has been treated from a medical, entomological and especially historical point of view.

These works, of a considerable extent, about 2,300 pages, are in the first tab, called Insecta . Numerous and accurate literature which is based has a very different origin and has been translated by myself. Complete work is available on this website, but separated by chapters, as you can see in the overall index. The idea is that the reader could easily find the specific subject he is looking for.

You will find a second tab, entitled Biographica . Here are included short biographies of several naturalists, scientists, geographers, historians or travelers who appear in my work, and for which I have great admiration; without their contribution I would not have written anything.

In third tab, called Etiam perire Ruinae , which mean "till ruins have disappeared" (Lucan. Farsalia , IX, 969), you will find maps of the ancient world. This is an ambitious work that I started on  2015. And maybe I never will finish it, its size is really considerable. The intention is to make a sort of tourist guide in the known world at the second century after Christ; what a traveler would find then: seas, rivers, mountain ranges, ethnicities, towns, cities or regions, all in its Latinized name.

The bibliography is based on the writings of ancient historians and geographers like Ptolemy, Pliny, Strabo, and many others who made minor contributions. Once drawn, I will upload the maps to the web, along with database "access" that supports them: there you will find all the information gathered and will facilitate you the location you are searching.

I have create that website to offer freely to you several contents of everything that I found interesting and I have learned and wrote. It does not seem fair to me that jobs remain invisible in a drawer, and I think it's not enough they remain limited to the published work. I want that my effort around many years collecting and processing much information could serve to anyone who feels interested in these matters than I have been really passionate.

Finally, you will find another tab, entitled Miscellanea ab absurdo : here are included phrases, ideas, short stories and thoughts that spin through my mind, often surrealist. I also need to open my head about "minor" questions, trivial if you prefer, but that produce to me comfort and pleasure. Here is shown another work of mine, nothing to do with the above, just a comedy that I wrote to laugh. I laughed a lot: Seven crimes per copulation (Plataforma, 2015), wrote by Margarito Micifú, a pseudonymous author… I had no courage to put my real name. I recommend you to see the book launch in the bookstore Abacus, it was really funny.
