how would you describe both the anopheles female and male mosquito?
how would you describe both the culicine female and male mosquito?
how would you describe the resting position of anopheles Gambiae and also its wing appearance
what mosquito is this and gender?
male anopheles (noted clubbed tips to palps and same length as proboscis)
what mosquito is this and gender?
male culicine (noted tips not clubbed)
