| | | |
− | *Specifically found in South America
| + | ==Hosts== |
| + | Humans, many birds and most domestic and wild animals. |
| | | |
| + | ==Identification== |
| + | The mature larvae may grow up to 25mm in length. ''D. hominis'' are similar to [[Calliphoridae|''Calliphora'']] in appearance, and are of the family [[Oestridae]]. They have a blue-black abdomen, and have yellow-orange head and legs. |
| | | |
− | '''Recognition'''
| + | Larvae are distinctive as they taper towards the posterior end. |
− | *Adult can grow up to 25mm in length

| | | |
− | *Similar to [[Calliphoridae|''Calliphora'']] in appearance
| + | ==Life cycle== |
− | **Blue-black
| + | The adults do not feed, and draw food from the larvae stage, which accumulate stores throughout their development. The female then catches an insect, most commonly the [[Culicidae|mosquito]], and lays a batch of eggs on it. |
− | **Yellow-orange head and legs
| |
| | | |
− | *Larvae are distinctive as they taper towards the posterior end
| + | The insect lands on a host, and the L1 larvae then hatch on the host, and quickly penetrate the skin. The larvae undergo a transformation to L2, and then subsequently to L3. The larvae fully mature, and then move to the ground to pupate. They then emerge later as adults. |
| | | |
| + | It is a '''4 month''' life cycle. |
