A misinterpretation of the fatty acid data led to the inclusion of C13:0 in the reported data throughout the article. The quantitative effect of this misinterpretation is limited. Please see the corrections below.

There is an error in Table 2 and its caption. Please see the correct Table 2 and caption here

Table 2. Dry matter (DM)%, crude protein, phosphorus, and total fatty acid (TFA) percentages on a DM basis, and fatty acid composition (as % of total fatty acids*) of diets provided to Blaptica dubia (BD), Hermetia illucens (HI), Tenebrio molitor (TM), and Acheta domesticus (AD).

There is an error in Table 4 and its caption. Please see the correct Table 4 and caption here.

Table 4. Dry matter (DM), crude protein (CP), phosphorus (P) content, and total fatty acids (TFA), of Blaptica dubia, Hermetia illucens, Tenebrio molitor without and with carrot supplementation, and Acheta domesticus on different diets (Mean ± SD).

Different superscripts in a column, per species, denote significant differences (Kruskal Wallis followed by Scheffé’s posthoc test; P<0.05).

Fig 1 and Fig 2 are incorrect. Please see the correct Fig 1 and Fig 2 here.

In the 3.1 Diet composition subsection of the Results and Discussion, there are errors in the third paragraph. The correct sentences are: The dietary fat composition varied between diets. The most prevalent fatty acids were palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1n9c), and linoleic acid (C18:2 n6c). The latter was especially abundant in control diets (45–60% of TFA). In the high fat diets, myristic acid (C14:0) was present in larger concentration (5–9% of TFA) than in the other diets (< 1%).

In the 3.4 Insect body composition subsection of the Results and Discussion, there are errors in the fourth sentence of the fourth paragraph. The correct sentence is: TFA content was more variable (22–34% of DM) than crude protein and P content, which were similar on most diets.

In the 3.4 Insect body composition subsection of the Results and Discussion, there are errors in the first sentence of the fifth paragraph. The correct sentence is: House crickets had a high crude protein (58–59% DM) and a low TFA content (17–20% DM) on the diets on which sufficient material for chemical analysis could be collected (the control and the high protein diets).

In the 3.5 Fatty acids subsection of the Results and Discussion, there are errors in the second sentence of the first paragraph. The correct sentence is: Capric acid (C10:0) was detected only in black soldier flies (0.7–1.3% of TFA; Table 6).

In the 3.5 Fatty acids subsection of the Results and Discussion, there are errors in the fourth sentence of the first paragraph. The correct sentence is: A small proportion of the house cricket fatty acids consisted of eicosatrienoic acid (C20:3n3; ≤0.5% of TFA), and docosahexaenoic acid (C22:6n3; ~0.1% of TFA).

In the 3.5 Fatty acids subsection of the Results and Discussion, there is an error in the seventh sentence of the second paragraph. The correct sentence is: However, none of the insect-diet combinations resulted in a n6/n3 ratio < 5.

In the 3.5 Fatty acids subsection of the Results and Discussion, there are errors in the second sentence of the third paragraph. The correct sentence is: The concentration of the latter fatty acid showed considerable variation due to dietary treatment (1.8–20.1% of TFA).

In the 3.5 Fatty acids subsection of the Results and Discussion, there is an error in the second sentence of the third paragraph. The correct sentence is: The main fatty acid in this species was C18:2 n6, although C16:0 and C18:1n9 were also present in high concentrations. Together these made up ≥75% of TFA.
