Hello ! We're french students and we're studying butterflies for our exams. We desperalty need the weight, the length, the wingspan, the beating frequency of these following butterflies: papilio phorcas papilio paris battus philenor siproeta epaphus papilion memnon parides sesostris greta oto Anartia amathea Dryas julia If it's possible, can you send us a picture of these butterflies on a sheet of graph paper ? Thanks a lot !
Unfortunately, I'm not certain that you'll be able to receive much help with these questions. The weight of a specimen isn't generally something lepidopterists measure... so I'd be surprised if anyone would have those statistics for you. As for the "beating frequency", as far as I've observed that's entirely contextually dependent, Take Papilios for example, at times they'll glide with relatively infrequent wing beats, whereas when visiting flowers they'll flap quite quickly but with very shallow movement... and then when they're patrolling it's different again. Wingspan should be easy enough for you to find on the internet, just be careful though as people measure wingspan differently; some from base of the forewing to the apex, others from one forewing apex to the other. As for "length"... length of what? If you mean wings, then this would be the same as wingspan. If you mean something else, I doubt it is common practice to measure the length of it.
As for the pictures on graph paper, that would take someone a fair amount of time to complete properly. Sorry for not being much help... but I must say I have difficulty understanding what exactly was assigned to your group... you may need to clarify with your teacher/professor exactly how they were expecting you to succeed in answering these questions.
