New Rarotonga moth

Hello lepidopterists.

This unusual moth turned up recently. I don't know what the larva feeds on. It looks like a Erechthias. I would appreciate more information on its identification and what it feeds on.

Many thanks

Gerald

Hi Gerald,

I would be looking in the Gelechiidae based on the hind wing outline. Have a look at the base of the proboscis to see if it is scaled, and check if the labial palps under all those scales have acute tips and are pointed upwards - that will at least confirm Gelechioidea.  

Dave.

Many thanks Dave,

It seems the palps are as you describe for Gelechiids and my moth fits well with other Gelechiids on the web.

However, the only Gelechiid I can find on the web with the strange "projections" on the forewing is in the genus Friseria from the Americas. My moth is obviously not a Friseria but the similarity of the forewing projections is interesting.

Thanks again.

Best regards, Gerald
