Las larvas m\u00e1s desarrolladas construyen y transportan un diminuto &#8220;estuche&#8221; protector elaborado con partes secas de las flores, desplaz\u00e1ndose como caracoles con su caparaz\u00f3n antes de dejarse caer al suelo para pasar el invierno protegidas en estuches sellados con seda. A diferencia de otras orugas que devoran hojas, estas se dirigen directamente a las semillas en desarrollo dentro de las cabezuelas del tr\u00e9bol rojo. Una sola larva puede destruir de dos a tres semillas al d\u00eda, alcanzando p\u00e9rdidas de hasta el 95% en infestaciones graves. Al alimentarse protegidas dentro de las flores individuales y sus estuches, los insecticidas convencionales apenas resultan efectivos.
