So, where should one start?
It is all about markers
- Teneral specimens in which the colours are not fully formed;
- Inaccessibility of some critical features such as elements within the genital capsule;
- Specimens that develop under exceptionally warm or cold conditions, whose patterns are greatly affected by temperature;
- Species with spring and summer broods and exhibit brood dimorphism; and
- Misinterpretation of dusting because of glare or rubbing.
