Dear Cohlinn,
We are going to handle your identification requests independently.  The insect that is pictured in three of your photos which you have described as “the brown and orange one have leaf-footed like feature” is actually a Leaf Footed Bug in the family Coreidae, and we believe we have identified it as a Citron Bug,
Leptoglossus gonagra, thanks to a photo posted on The Flying Kiwi.  According to Citrus Pests ID Tools, its worldwide distribution is “Cape Verde Islands, the Caribbean, Central America, Indonesia, Malaysia, Mexico, Pacific Islands, Papau New Guinea, and South America” but the native range is “not reported.”  The undeveloped wings indicate that this is an immature specimen.  Though the Citron Bug is reported from North America, BugGuide does not have any images of an immature individual.  Discover Life, which does not provide a photo, indicates the common name is Passionvine Bug.  The red nymphs pictured on Nature Love You are much younger than your nymph.  We cannot locate an image of an immature Citron Bug that resembles your individual, and we are basing our identification on the orange markings on the ventral view which resemble the markings on the adult, including the individual posted on Forestry Images.

Hi Daniel,
Thank you so much for your hard work! I did not expect an immature version of the Citron bug. That’s probably why I couldn’t find any pictures of a bug with a single large orange dot on the back. I think you are right. IDTools mentioned that it is pest to passion fruit and there are passion fruit vines right next to the loofah plant I caught these in. Now I know what’s been marring the passion fruit skins.
Thank you again.
Cohlinn
