R. cruentatus (Anyone here from FL?)

I've been wanting to try sago grubs (R. ferrugineus) for years. Unfortunately importing them into the U.S. is illegal.

R. cruentatus (palm/palmetto weevil) is closely related to the sago grub and can be found in the U.S. (primarily FL but I've also heard of them being found in TX and CA.)

Has anyone had the opportunity to try the palm weevil larvae? If so could you share your opinion on their flavor?


  • Rhynchophorus is an edible family of palm worm (weavil) with some variation in appeal (see 4th link) variety are edible; R. cruentatus are worth trying . Ibo (Nigeria) first remove their variety of palm worm laval "guts" by plucking off the abdomen's end, then wash & fry larvae in onion & spices. In Cameroon they are thoroughly washed, their abdomen pierced with bamboo skewer to discharge viscous fluid & cooked grilled/fried/stewed.

    Here's an artificial diet for rearing a Rhynchophorus variety on oat & white beans for 1st 3 instars; then shifting to oat & fiber for instars 4 -5. The addition of brewer's yeast would be essential, a bit of salt, some carbohydrate ("sugar") & molasses (minerals).(2001) "MASS REARING OF THE RED PALM WEEVIL, RHYNCHOPHORUS FERRUGINEUS OLIV., ON SUGARCANE AND ARTIFICIAL DIETS FOR LABORATORY STUDIES: ILLUSTRATION OF METHODOLOGY" ; free full text = http://www.iraqi-datepalms.net/Uploaded/file/Paper 4 Mass Rearing 344-357.pdf

    For some nutritional composition see Table 1 & observation that they can be reared on banana/plantain (cooking banana) material. Researchers washed the Amazonian larvae in lemon &/or vinegar before flouring for frying up.

    According to the following study they've " ... been successfully cultured on cut petiole or stem tissue of coconut palms ...sugarcane ... date palm trunks ... sugarcane bagasse (fibre), coconut cake, yeast, sucrose, minerals, vitamins ... & ... semi artificial diet containing wheat flour, corn flour, shredded date palm fronds and water ." The authors used what might be called sheaves of palm ("bolts"); since these may not be readily available creating sheaves of bannana/plantain plant fiber might (?) be an alternative.

    In 1989 Rhynchophorus cruentatus were reared initially on pineapple husk segments (syncarp) & then shifted to sugar cane to fulfill their cycle. http://www.jstor.org/discover/10.2307/3495186?sid=21106048848533&uid=2&uid=4
