There was a lot of work on the wax of a certain scale insect in the US about 1960-75. That dry land species produces what might be potentially commercial amounts. However, that was a long time ago and I forget the details. Try Google Scholar.
A quick search gave the following article: https://www.researchgate.net/publication/226729934_The_composition_of_beeswax_and_other_waxes_secreted_by_insects
Article The composition of beeswax and other waxes secreted by insects
I think mealybug wax such as other Waxes are organic compounds that characteristically consist of long alkyl chains. Synthetic waxes are long-chain hydrocarbons (alkanes or paraffins) that lack substituted functional groups. Natural waxes may contain unsubstituted hydrocarbons, such as higher alkanes, but may also include various types of substituted long chain compounds, such as fatty acids, primary and secondary long chain alcohols, ketones and aldehydes. They may also contain esters of fatty acids and long chain alcohols. For more information please see attach file. Best regards
