La mayor parte del alimento de una planta proviene de la fotosíntesis. Las plantas pueden recoger otros elementos, como nitrógeno o fósforo, a través de sus raíces. Si el suelo no tiene esos elementos, algunas plantas pueden agarrarlos capturando presas, generalmente insectos, y digiriéndolas. Sus hojas no son un lugar saludable para un insecto, por lo que una mosca como Toxomerus basalisla mosca de la drosera, es un rompecabezas.

Un estudio reciente de Andreas Fleischmann y colegas ha encontrado que esta mosca pone sus huevos en o cerca de las droseras. Sundews recibe su nombre de sus trampas. Tienen hojas con what insect is eating my plants, y los pelos tienen un pegamento pegajoso que brilla, como el rocío, al sol. Se ven bonitos, pero son mortales. Una mosca que aterriza para investigar lo que podría parecer un refrigerio what insect is eating my plants atasca en el pegamento y lucha.

Estas luchas activan las hojas. Finalmente, toda la hoja se enrolla alrededor de la presa y la planta libera enzimas para digerir a la desafortunada criatura. Las hojas son muy efectivas, por lo que cuando una drosera quiere atraer a un polinizador, se asegura de que sus flores estén bien alejadas de las hojas. De esa manera, no carga al insecto con polen antes de comérselo. La eficacia de la drosera como asesino no es solo una amenaza. También es una oportunidad. Envolver una hoja alrededor de una víctima lleva tiempo.

Este es el caso de la mosca de la drosera. Un trabajo anterior de Fleischmann y sus colegas mostró que si un rocío de sol podía atraparlo, entonces una larva de Sundew Flower Fly estaba feliz de intentar comerla. La vida de una mosca de la drosera comienza en la parte inferior de una hoja de la drosera. La ubicación se debe a que la hembra Sundew Flower Fly no es suicida y aterriza en la trampa para poner sus huevos. Las moscas pueden escapar de las trampas si no golpean demasiados pelos, pero no es una buena idea golpear demasiados deliberadamente.

Una vez que eclosionan, las larvas se sientan en las hojas, esperando. Si se sentían amenazados, se retiraban a la roseta de la planta y se escondían en la base de las hojas. Una vez que sienten las vibraciones de la presa que lucha, se mueven hacia las hojas para encontrarla y comerla. El equipo había pensado que las larvas buscarían presas muertas. De hecho, encontraron a las larvas como what are symbiotic association alimento fresco y vivo.

Esperaron hasta que la presa dejó de moverse antes de atacar. La respuesta podría estar en cómo las droseras atrapan y detectan a sus presas. Un factor importante en la activación de la trampa de la drosera es una lucha repetida en el mismo lugar. Sin embargo, las droseras no solo usan el sentido del tacto para how to stop expecting in a relationship presas.

También saben. Los pelos de sundews son quimiotrópico, lo que significa que se mueven hacia ciertos productos químicos. Fleischmann y sus colegas argumentan que la composición química de la baba de la larva podría actuar como un camuflaje. Los autores también propusieron una explicación alternativa. Después de alimentarse, las larvas pupan en la parte inferior de las hojas de la drosera.

Esto lleva unos días. Luego, cuando son adultos, se alimentan del polen de las flores de la drosera.

Los insectos asesinos viven en la planta y se alimentan de los insectos que Rorídula trampas Lo que entra también sale, pero los desechos que arrojan las chinches asesinas son estiércol fresco que Rorídula puede digerir. Hay muchas otras plantas que tienen trampas pegajosas para defenderse e insectos que han aprendido a explotar a las víctimas que quedan atrapadas. Una drosera es una gran ventaja para una mosca con las habilidades adecuadas. What insect is eating my plants sorprende que Fleischmann y sus colegas observaran moscas de ambos sexos mostrando un comportamiento territorial alrededor de las plantas.

Irónicamente, una planta que busca matar insectos ha terminado siendo custodiada por otra que la encuentra esencial para su historia de vida. Fleischmann, A.
