¡Hola! Bienvenidos al blog Cicindelica. Este espacio está dedicado principalmente a los Cicindelidae de España, aunque también podemos tratar a especies de otros lugares. El objetivo es abierto, simplemente acumular y divulgar conocimiento acerca de estas fantásticas criaturas. Espero que sea una herramienta útil y agradable para este fin.

¿Cómo reconozco una cicindela?
Las cicindelas son muy fáciles de distinguir de otros grupos de insectos. Con un poco de práctica, y una vez nos familiaricemos con su aspecto, la distinción entre una cicindela y cualquier otro escarabajo será tan obvia que no será necesario pararnos a clasificarla a nivel de familia.
Los cicindélidos se reconocen fácilmente como escarabajos o coleópteros, ya que presentan el par de alas anterior adaptado para formar unos estuches protectores rígidos o élitros, que cubren completamente las alas membranosas empleadas para el vuelo, las cuales quedan dobladas bajo los élitros.
Dentro de los coleópteros, los cicindélidos se diferencian fácilmente de los carábidos, la familia más cercana, por la posesión de unos ojos prominentes que, junto con la cabeza, superan en anchura al pronoto (la parte visible dorsalmente del tórax); y por la carencia de estriación en los élitros. Las antenas se insertan además justo delante de los ojos, en contraste con la posición más lateral que presentan los carábidos.
Tiger beetles are very easy to distinguish from other insect groups. With a bit of practice, and once we are familiar with their appearance, the distinction between a tiger beetle and any other kind of beetle will be so obvious that we won't even have to stop and try to recognize it as such.
Cicindelids are easily identified as beetles (order Coleoptera) because of their hardened forewings, known as elytra (sing. elytron), that cover the membranous hindwings used for flight, which remain folded under the elytra until flight takes place.
Within the Coleoptera, Cicindelids can be easily separated from Carabids, their closest relatives, thanks to their protruding eyes that, together with the head, are always wider than the pronotum (the dorsally visible part of the thorax), and thanks to the lack of sculptured lining on the elytra.

¿Qué son las cicindelas?
Las cicindelas o "escarabajos tigre" en inglés son un singular grupo de insectos pertenecientes al orden Coleoptera (escarabajos). La mayoría de taxónomos los considera una familia independiente de los cárabos, sus parientes más cercanos, y nosotros tomaremos este enfoque en el blog.
¿Por qué nos "gustan" las cicindelas?¿Qué las hace interesantes? Estos insectos, menos conocidos por el gran público que las mariquitas o las mariposas diurnas, han cautivado sin embargo a cierto número de aficionados, nosotros entre ellos. No resulta fácil explicar qué hace a estos insectos tan apasionantes, y la mejor manera es verse expuesto personalmente a ellos. De todas formas, podrían ser los variados colores y patrones de sus iridiscentes cuerpos, o el estilo de vida activo, veloz y rapaz que desarrollan en pleno mediodía, o seguramente una combinación de varias cosas difícil de determinar.
Se conocen más de 2600 especies de cicindélidos en todo el mundo, de las cuales 23 forman parte de la fauna española. La historia natural, dinámica poblacional, comunidades y patrones de distribución mundial, así como las relaciones taxonómicas de los grupos que componen esta familia son temas que se han estudiado más a fondo en los Cicindelidae que en muchos otros insectos. Además de su interés intrínseco, los Cicindelidae son un organismo modelo especialmente adecuado para muchos estudios biológicos. Los estudios genéticos del DNA nuclear y mitocondrial de estos coleópteros tienen en muchos casos repercusiones globales en la comprensión de muchos otros organismos, y las investigaciones sobre los mecanismos de producción de colores cuticulares, detección de ultrasonidos, sistemas visuales, anomalías genéticas excepcionales, patrones de distribución y riqueza de especies se han desarrollado en gran medida estudiando cicindélidos. Nos encontramos por tanto ante un grupo de insectos que además de tener una gran belleza como pasatiempo o tema lúdico, tiene un gran valor científico.
Tiger beetles are a singular insect family belonging to the order Coleoptera (beetles). Most taxonomists consider them a separate family independent from the Carabidae, their closest relatives, and we will take this approach in the blog.
Why do we like tiger beetles? What makes them interesting? These insects, altough not as well known as ladybugs and butterflies, have captured the interest of a number of enthusiasts, us among them. It is not easy to explain what makes these insects so thrilling, and the best way would be to come into direct contact with them. However, it may be the varied colors and patterns displayed on their iridescent bodies, or the active, quick and ferocious lifestyle they develop at the hottest time of the day, or most likely a combination of these hard to define.
More than 2600 species of cicindelids are known worldwide, of which 23 are present in Spain. The natural history, population dynamics, comunities and distributional patterns, as well as the taxonomic relationships within the family, are issues that are better known in the Cicindelidae than in many other insect groups. Apart from their intrinsical interest, tiger beetles are a good animal model for many different biological studies. Genetic studies on the nuclear and mitochondrial DNA of these beetles often have global consequences in the understanding of other organisms, and investigations on the mechanisms of cuticular color production, ultrasound detection, visual systems, exceptional genetic anomalies, range patterns and species richness have been developed using cicindelids. We therefore find ourselves in front of a group of insects that has a great scientifical value in addition to being a very interesting hobby.
